Description

一种显影盒 技术领域

背景技术
电子照相方式的图像形成装置具备可拆卸的显影盒，显影盒安装于图像形成装置的鼓框架上，显影盒上的显影辊向鼓框架上的感光鼓提供显影剂，使得感光鼓形成静电潜像。
显影辊与感光鼓长时间接触会使得显影辊与感光鼓受损，因此显影盒上一般会设置分离件，分离件用于接收图像形成装置施加的分离力，在不需要显影盒工作时，使得显影辊与感光鼓脱离接触以防止显影辊和感光鼓受损，保证图像形成装置的成像品质。但是复杂的分离件结构不利于显影盒的小型化，也不利于显影盒生产成本的控制。

如图5、图13-图14所示，护盖21位于盒体10的第一侧端11，护盖21以可拆卸的方式固定安装在盒体10上，护盖21不相对于盒体10移动，护盖21可与盒体10共同运动，护盖21不对送粉辊进行轴向限位。
护盖21包括第一引导件211、驱动保护部212、第一承重部213、分离件214和第一校正部215，优选各部件可与护盖21一体成型，也可以是以可拆卸的方式组合固定安装护盖21上。
第一引导件211包括第一上引导部和第一下引导部，第一上引导部和第一下引导部均沿第一方向D1向远离第一侧端11的方向突出，第一上引导部和第一下引导部均为圆弧状，第一上引导部和第一下引导部之间被缝隙隔开，即第一引导件211可视为一个圆柱体沿径向被分割为两个圆弧状突起，该缝隙位于显影辊131与感光鼓921接触的接触位置与显影辊131旋转轴线的连线的延长线上，可通过第一上引导部和第一下引导部之间的缝隙观察辊轴1312的转动情况从而判断显影辊131是否能够正常工作，也可便于第一引导件211与显影辊131的辊轴1312的对位进而便于护盖21的安装。
第一引导件211环绕显影辊131的辊轴1312的第一端部13121但不与辊轴1312接触，防止因显影辊131转动与第一引导件211之间产生摩擦从而影响显影辊131的正常工作，在其他实施例中，第一引导件211可以与辊轴1312接触。在另一些实施例中，第一引导件211可以是一个完整的中空圆柱体环绕显影辊131的第一端部13121，或者第一引导件211仅包括第一上引导部或者第一下引导部，可根据实际需求设计第一引导件211的形状。
驱动保护部212用于保护驱动部，驱动保护部212包括沿第一方向D1贯穿护盖21的通孔，通孔用于暴露动力接收部40，便于动力接收部40接收来自图像形成装置 输出的动力，在第二方向D2上驱动保护部212位于第一引导件211的上方。
第一承重部213为沿第一方向D1向外突出的突起，本实施例中第一承重部213为圆弧状突起，在其他实施例中可为其他形状，第一承重部213包括圆弧面，第一承重部213用于在显影盒1安装在鼓框架92的状态下，使得圆弧面与鼓框架92内的部件接触以支撑显影盒1的重量，在第三方向D3上第一承重部213与驱动保护部212至少部分重叠。
分离件214为沿第一方向D1向外突出的突起，在第二方向D2上分离件214至少部分比驱动保护部212更远离显影辊131，从第二方向D2观察分离件214至少部分与驱动保护部212重叠，在第三方向D3上相对于第六侧端16分离件214更靠近第五侧端15，分离件214用于接收图像形成装置施加的分离力以使得显影辊131与感光鼓921分离。
分离件214包括用于接收图像形成装置输出的分离力的受力部，受力部包括第一受力块2141，第一受力块2141固定设置在第一侧端11处，即第一受力块2141不可相对于盒体10运动，第一受力块2141上设有第一斜面2142，第一斜面2142可受图像形成装置内的分离力输出件91抵接以接收分离力，第一斜面2142为延伸方向与第一方向D1交叉的斜面或者弧面，本实施例优选为斜面，进一步，第一斜面2142相对于第一方向D1倾斜，第一斜面2142在第一方向D1上从左至右沿第三方向D3朝着靠近显影辊131的旋转轴线的方向延伸，进一步第一斜面2142在第一方向D1上从左至右沿第三方向D3朝着靠近第六侧端16的方向延伸，即第一斜面2142的起始端21421比末端21422在第一方向D1上更靠近第二侧端12，且起始端21421比末端21422在第三方向D3上更远离第六侧端16。第一斜面2142与第一方向D1之间的α夹角范围为38°-58°，本实施例优选为48°。
第一斜面2142接收分离力时与盒体10共同运动，使得显影盒1在第三方向D3上发生移动，进一步为朝向远离感光鼓321的方向运动，进而使得显影辊131与感光鼓921分离。可知的是，分离件214可直接安装在盒体10上或者其他部件上。
可知的，驱动部的旋转轴线与显影辊131的旋转轴线连线的延长线L3穿过第一受力块2141，进一步，驱动部的旋转轴线与显影辊131的旋转轴线的连线的延长线穿L3过第一斜面2142，由于在显影盒1安装至鼓框架92上后，邻近显影辊131位于第一侧端11的一端处和驱动部处均可受鼓框架92一定的支撑，故可使得第一斜面2142更稳定的接收分离力。
第一校正部215为沿第三方向D3延伸形成，在第二方向D2上第一校正部215比驱动保护部212更远离显影辊131，第一校正部215用于在显影盒1安装在图像形成装置的过程中，在显影盒1安装不到位的情况下，第一校正部215受图像形成装置内的部件抵接，使得显影盒1受力移动而位于安装位置。
如图15-18所示，显影盒1后端在靠近第一侧端11的位置设置有第一迫推部23，显影盒1后端在靠近第二侧端12的位置设置有第二迫推部24，即本实施例中迫推部包括第一迫推部23和第二迫推部24，第一迫推部23和第二迫推部24均包括大致为平面的压力接收面，压力接收面用于与鼓框架92直接接触以接收鼓框架92在第三方向D3上施加的迫推力。在第二方向D2上，第一迫推部23和第二迫推部24的压力 接收面到显影辊131的距离L2大于第一承重部213到显影辊131的距离L1。
本实施例中第一迫推部23和第二迫推部24均为与盒体10一体成型，且不相对于盒体10突出，在其他实施例中第一迫推部23和第二迫推部24可以可拆卸的固定安装于盒体10上。第一迫推部23和第二迫推部24在第一方向D1上重叠设置，以保证显影辊131与感光鼓921接触的位置受力程度一致。在其他实施例中，第一迫推部23和第二迫推部24可不重叠设置，或者仅设置一个迫推部。在显影盒1安装到图像形成装置内的鼓框架92上后，第一迫推部23受到鼓框架92上的第一迫推件9231在第三方向D3上施加的迫推力，第二迫推部24受到鼓框架92上的第二迫推件9241在第三方向D3上施加的迫推力，使得显影盒1始终具备在第三方向D3上向感光鼓靠近921的趋势，使得显影辊131与感光鼓921紧密接触，保证图像形成装置的成像品质。
如图18所示，盒体10的第二侧端12设置有第二承重部122，第二承重部122为沿第一方向D1向远离第二侧端12的方向延伸。第二承重部122与第一承重部213的作用相同，均为在显影盒1安装在鼓框架92的状态下与鼓框架92接触以支撑显影盒1，即本实施例中承重部包括第一承重部213和第二承重部122，且为了使得显影盒1的设计美观和保持显影盒1在图像形成装置内的平衡，第二承重部122与第一承重部213形状相同，均为圆弧状突起，且第二承重部122与第一承重部213在第一方向D1上重叠设置。
在显影盒1安装到图像形成装置的鼓框架92的状态下，第一承重部213与鼓框架92上的第一平台部9232接触，第二承重部122与第二平台部9246接触，使得显影盒1稳定安装在鼓框架92内。其他实施例中，第二承重部122与第一承重部213形状可不相同，第二承重部122与第一承重部213也可不重叠设置，或者仅设置一个承重部。可知的是，在第二方向D2上第一迫推部23和第二迫推部24的压力接收面到显影辊131的距离大于第二承重部122到显影辊131的距离。
如图5、图16、图18-图20所示，识别组件包括支架22和存储介质221。存储介质221用于存储显影盒1的型号、新旧等信息，存储介质221可拆卸的安装在支架22上，存储介质221包括用于与图像形成装置接触内的电触头9242接触的电接触面，电接触面在第三方向D3朝向第六侧端16，存储介质221通过电接触面将显影盒1信息传递至图像形成装置，使得显影盒1被图像形成装置识别。
支架22可拆卸的固定安装在盒体10在第一方向D1上的第二侧端12，支架22包括容纳部222、第二校正部223、***部224和引导部225，各部件可与支架22一体成型，也可以是组合而成。
在第二方向D2上容纳部222位于第二校正部223的下方，容纳部222为在第三方向D3上凹陷的凹槽，容纳部222用于容纳存储介质221，优选存储介质221和支架22不可相对于盒体10运动。第二校正部223与第一校正部215作用相同，用于在显影盒1安装在图像形成装置的过程中，在显影盒1安装不到位的情况下，第二校正部223受图像形成装置内的部件抵接，使得显影盒1受力移动而位于安装位置，第二校正部223同样具有在第三方向D3上延伸的部分，在其他实施例中，可不设置第一校正部215和第二校正部223，通过人为施加力使得显影盒1位于安装位置，或者仅 设置一个矫正部。
***部224为在第一方向D1上延伸的卡扣件，支架22通过***部224***到盒体10上的凹槽内从而安装到盒体10上，再通过螺钉固定。容纳部222和引导部225位于支架22在第三方向D3上的不同侧，引导部225为沿第一方向D1延伸的圆柱体，引导部225包括有圆周表面，在支架22安装在盒体10的状态下，在显影盒1大致沿第二方向D2安装到图像形成装置的过程中，引导部225用于与鼓框架92上的突出部9243接触，即引导部225的圆周表面与突出部9243接触，并在安装过程中受突出部9243引导，沿着突出部9243的延伸方向支架22安装到预定位置，并使得存储介质221与电触头9242接触，保证显影盒1被图像形成装置识别。在本实施例中，为了使得存储介质221能够顺利位于与电触头9242接触的接触位置和减少引导部225和突出部9243接触产生的摩擦力，引导部225设置为圆柱体，用圆柱体的圆柱表面与突出部9243接触，在其他实施例中，引导部225可设置为其他形状，或者不设置引导部225。
如图16和图18所示，盒体10还设置有灌粉口121和灌粉盖123，灌粉口121为盒体10沿第一方向D1贯穿第二侧端12的通孔，显影剂通过灌粉口121灌送至盒体10的容纳腔内。灌粉盖123为匹配灌粉口121通孔形状而设置的盖件，本实施例中，灌粉口121和灌粉盖123均为圆形，在其他实施例中可为其他形状。在显影剂灌送至容纳腔内后，为了防止显影剂通过灌粉口121泄露，灌粉盖123完全覆盖灌粉口121，即在第一方向D1上灌粉口121和灌粉盖123完全重叠。可知的是，位于第二侧端12的灌粉盖123与支架22无任何重叠与干涉。
如图16、图18和图21所示，盒体10第二侧端12设置有第一轴承25，第一轴承25通过螺钉可拆卸的固定安装在第二侧端12，第一轴承25包括第二引导件251、显影孔252、送粉孔253和主体254，主体254为板状件，第二引导件251、显影孔252和送粉孔253可以与主体254一体成型，也可以是可拆卸的安装在主体254上。第二引导件251为从主体254上沿第一方向D1向远离第二侧端12的方向突出，第二引导件251不相对于盒体10运动，第二引导件251包括第二上引导部和第二下引导部，第二上引导部和第二下引导部通过一条缝隙分隔开，该缝隙位于显影辊131与感光鼓921接触的接触位置与显影辊131旋转轴线的连线的延长线上，第二上引导部和第二下引导部均为圆弧状突起，第二引导件251与第一引导件211形状相同，均可被视为一个圆柱体被沿径向分割为两个圆弧状突起。第二引导件251环绕显影辊131的第二端部13122，可可通过第二上引导部和第二下引导部之间的缝隙观察第一轴25与显影辊131的辊轴1312的安装对位，又可以观察辊轴1312的转动情况。
第二引导件251与第一引导件211共同组成引导组件，在显影盒1安装到图像形成装置的过程中对显影盒1起引导作用，使得显影盒1顺利安装到图形成装置。从第一方向D1观察，第二引导件251与第一引导件211重叠设置，保持显影盒1在安装过程中的平衡，使得显影盒1能够更为稳定地安装，在其他实施例中第二引导件251与第一引导件211可不重叠设置，或者仅设置一个引导件。在其他实施例中，第二引导件251可以是一个完整的中空圆柱体环绕显影辊131的第二端部13122，或者第二引导件251仅包括第二上引导部或者第二下引导部，可根据实际需求设置第二引导件 251的形状。
显影孔252和送粉孔253均为沿第一方向D1贯穿主体254的通孔，显影辊131的第二端部13122***显影孔252中，第二端部13122穿过第二侧端12并部分位于第二侧端12之外，第二端部13122被显影孔252可旋转地支撑。送粉孔253在第一方向D1上位于第二侧端12的一端***到送粉孔253中，从而使得送粉辊在第一方向D1上位于第二侧端12的一端被第一轴承25可旋转地支撑。
可知的是，第一轴承25由导电材料制成，即本实施例中第一轴承25的第二引导件251为显影盒1的电接收部，第二引导件251可与电极9245接触进而接收来自图像形成装置输出的电能，并将电能传输至第一轴承25，第一轴承25将电能传输至被第一轴承25支撑的显影辊131和送粉辊，使得显影辊131和送粉辊带电，使得显影辊131和送粉辊吸附显影剂。
如图22-23所示，在显影盒1安装在图像形成装置的鼓框架92上后，显影盒1上的分离件214位于鼓框架92的第一间隔9233内的第一位置，并在第三方向D3上相对于第二槽壁92332分离件214更靠近第一槽壁92331，显影盒1上的显影辊131和图像形成装置上的感光鼓921处于紧密接触状态，以使得显影辊131能够更好的为感光鼓921提供显影剂。
如图5、图24-25所示，在图像形成装置不需要显影盒1工作时，图像形成装置会发出指令，使得显影辊131和感光鼓921脱离接触，防止因长时间接触使得显影辊131和感光鼓921受损。
图像形成装置的分离力输出件91开始沿第一方向D1向左移动并开始抵接在分离件214的第一斜面2142上，分离力输出件91对分离件214施加分离力，由于第一斜面2142为相对于第一方向D1倾斜的斜面，所以分离力输出件91可在第一方向D1上移动的过程中，抵接在第一斜面2142的不同位置，即分离力输出件91在第一斜面2142上相对于第一斜面2142从末端21422向起始端21421移动。由于在第三方向D3上起始端21421比末端21422更远离第六侧端16，同时第一斜面2142将此分离力分解为一平行于第三方向D3的作用力，并将该作用力传动至盒体10，所以分离件214在受分离力输出件91不断抵接的过程中在第三方向D3上向后移动，进而带动显影盒1在第三方向D3上向后移动。
进一步为盒体10以显影辊131左端(位于第二侧端12的一端)与感光鼓921左端接触的位置为枢轴点进行枢转，使得第一侧端11以摆动的方式向后移动，进而使得显影辊131右端(位于第一侧端11的另一端)向后摆动从而移动到显影辊131与感光鼓921分离的位置。本实施方式中，定义左端为靠近第二侧端12的一端，右端为远离第二侧端12的一端。
当分离力输出件91停止移动时，分离力输出件91仍然与分离件214保持抵接关系，分离件214位于第一间隔9233的第二位置，在第三方向D3上分离件214在第二位置时与第一槽壁92331的距离大于分离件214在第一位置时与第一槽壁92331的距离。
可知的是，在分离件214受抵接带动显影盒1在第三方向D3上向后移动时，为了使得显影盒1的移动更为顺畅和稳定，第一承重部213在第一平台部9232的延伸 方向上向后移动，第二承重部122在第二平台部9246的延伸方向上向后移动，本实施例中第一承重部213和第二承重部122移动的距离不同，在其他实施例中，第一承重部213和第二承重部122移动的距离可相同。
可知的是，在分离件214受抵接带动显影盒1在第三方向D3上向后移动时，显影辊131与感光鼓921由紧密接触状态开始逐渐向脱离接触状态改变，即显影辊131在不断远离感光鼓921，在分离件214位于第一间隔9233的第二位置时，显影辊131的右端与感光鼓921完全脱离接触，并在分离力输出件91与分离件214抵接的状态下保持脱离接触。
可知的是，在分离件214受抵接带动显影盒1在第三方向D3上向后移动时，显影盒1上的第一迫推部23和第二迫推部24分别与第一迫推件9231和第二迫推件9241分别保持接触，且使得第一迫推件9231和第二迫推件9241在第三方向D3上向后移动。本实施例中，第一迫推件9231和第二迫推件9241在第三方向D3上向后移动距离不同，在其他实施例中，第一迫推件9231和第二迫推件9241在第三方向D3上向后移动距离可相同。
当显影盒1再次工作时，图像形成装置发出指令使得分离力输出件91沿第一方向D1向右移动，分离件214不再受分离力输出件91的抵接，在第一迫推件9231和第二迫推件9241具备的弹性作用下，显影盒1沿第三方向D3向前运动，显影辊131与感光鼓921紧密接触，显影盒1在图像形成装置内正常工作。
第二种实施方式
本实施方式除特别说明的部分外，其他部分与第一种实施方式相同。
如图26所示，本实施例展示了一种盒体1a的具体结构，盒体1a包括盖体17a和壳体18a，盖体17a与壳体18a通过可以通过焊接、粘接、螺钉连接等方式固定连接在一起，本实施例中盖体17a与壳体18a通过超声波焊接工艺连接在一起形成盒体1a。容纳仓19a位于盖体17a与壳体18a围合而形成的空间内。盒体1a的第一侧端11a、第二侧端12a、第三侧端13a、第四侧端14a、第六侧端16a由壳体18a形成，盒体1a的第五侧端15a由盖体17a形成。
如图27所示，盒体1a下端形成有出粉口，壳体18a上一体成型有支撑部181a，支撑部181a在盒体1a的第一侧端11a和第二侧端12a之间延伸并且与第一侧端11a和第二侧端12a连接，支撑部181a用于支撑和固定安装刀架21a，支撑部181a上设置有至少一个第一定位孔1811a，第一定位孔1811a用于供螺钉***，刀架21a上开有至少一个第二定位孔211a，第二定位孔211a与第一定位孔1811a对齐，刀架21a通过螺钉固定安装到支撑部181a上，螺钉大致沿着第二方向D2穿过第二定位孔211a并***第一定位孔1811a，从而将刀架21a固定在支撑部181a上，本实施例中第一定位孔1811a和第二定位孔211a的数量均为两个，且对称的设置在刀架21a在第一方向D1上的两端部。从而使得刀架21a被第一侧端11a和第二侧端12a支撑，并且刀架21a固定在支撑部181a上利用刀架21a自身的强度可以防止支撑部181a受到外力时产生形变，进而防止壳体18a产生形变。
盖体17a上设置有第一焊接面171a，壳体18a上设置有与第一焊接面171a在第三方向D3上对齐的第二焊接面182a，盖体17a装配到壳体18a上后第一焊接面171a 和第二焊接面182a重合，并且驱动部在第一方向D1上的投影与第一焊接面171a和第二焊接面182a不重合。使得可以先把驱动部安装到壳体18a上再焊接盖体17a，并且盖体17a装配到壳体18a的过程中盖体17a不会碰到驱动部，避免驱动部被盖体17a撞击而脱落。
如图29所示，盒体1a的第六侧端16a上一体成型的形成有分隔壁183a，分隔壁183a和支撑部181a将容纳仓19a分隔为显影仓192a和显影剂容纳仓191a，在第二方向D2上，显影仓192a位于显影剂容纳仓191a的下方，支撑部181a与分隔壁183a之间形成有连通口193a，连通口193a连通显影剂容纳仓191a和显影仓192a，显影辊131a、送粉辊132a可旋转的设置在显影仓192a内，搅拌架31a可旋转的设置在显影剂容纳仓191a内，出粉口位于显影仓192a下端并使得显影仓192a通过出粉口与盒体1a外部连通，显影辊131a的圆周面通过出粉口暴露至盒体1a外部。通过支撑部181a与避免显影剂容纳仓191a内的显影剂过多的进入显影仓192a内，导致送粉辊132a、显影辊131a处堆积的显影剂过多，转动阻力增大的问题。
如图28和图29所示，本实施例展示了一种搅拌架31a的具体结构，搅拌齿轮45a同轴固定安装于搅拌架31a的右端，搅拌架31a随搅拌齿轮45a一起旋转，搅拌架31a上固定安装有搅拌叶片32a，搅拌叶片32a随搅拌架31a一起旋转，搅拌架31a旋转时带动搅拌叶片32a旋转从而搅动容纳仓19a内的显影剂。
搅拌架31a的旋转轴线在第二方向D2上位于显影辊131a的旋转轴线和把手141a之间，搅拌架31a的旋转轴线在第二方向D2上位于电接触面7a与显影辊131a的旋转轴线之间，搅拌架31a的旋转轴线在第二方向D2上位于分离件1112a与显影辊131a的旋转轴线之间，搅拌架31a的旋转轴线在第三方向D3上位于第一迫推部161a与分离件1112a或者第二迫推部162a与分离件1112a之间。
如图30和图31所示，第一承重部1111a和第二承重部1211a在第一方向D1上的投影与搅拌架31a在第一方向D1上的投影重合，可以是全部重合也可以是部分重合，本实施例中为部分重合。通过以上设计，使得搅拌架31a相较于现有技术更靠近显影辊131a和送粉辊132a，从而使得堆积在连通口193a处、送粉辊132a处的显影剂能够被更充分的搅动，避免结块以及过多的堆积。并且还可以使得搅拌齿轮45a可以设置得更靠近显影辊131a齿轮和送粉辊132a齿轮，从而使得齿轮排布更加紧凑，有利于显影装置的体积小型化。
如28和图32所示，盒体1a的第一侧端11a和第二侧端12a上沿着第一方向D1开有呈圆形的第一搅拌架支撑孔116a和第二搅拌架支撑孔126a，第一搅拌架支撑孔116a沿着第一方向D1贯穿盒体1a的第一侧端11a，第二搅拌架支撑孔126a沿着第一方向D1贯穿盒体1a的第二侧端12a，搅拌架31a在第一方向D1上的两端分别***第一搅拌架支撑孔116a和第二搅拌架支撑孔126a内并被第一搅拌架支撑孔116a和第二搅拌架支撑孔126a可旋转的支撑，搅拌架31a上还套设有密封圈，密封圈被搅拌架31a和第一搅拌架支撑孔116a与第二搅拌架支撑孔126a挤压而产生形变进而对第一搅拌架支撑孔116a和第二搅拌架支撑孔126a进行密封，避免显影剂容纳仓191a内的显影剂泄露。同时由于搅拌架31a需要产生旋转运动，为了避免搅拌架31a旋转过程中密封圈从第一搅拌架支撑孔116a内滑脱，因此搅拌齿轮45a套设在搅拌架31a 上的同时还会对第一搅拌架支撑孔116a内的密封圈起到限位效果，阻挡密封圈从第一搅拌架支撑孔116a滑脱。
如图31、图32、图33、图34、图35所示，本实施例还展示了一种支架121a与第一轴承5a的具体结构，相较于实施例一中的支架，本实施例中的支架121a包括盖部1212a，盖部1212a一体成型于支架121a上，盖部1212a在第一方向D1上的投影覆盖第二搅拌架支撑孔126a在第二方向D2上的投影，盖部1212a朝向盒体1a的一面上一体成型有限位柱12124a，限位柱12124a***第二搅拌架支撑孔126a内进而阻挡第二搅拌架支撑孔126a内的密封圈从第二搅拌架支撑孔126a内滑脱。第二承重部1211a一体成型的设置在盖部1212a上。
盖部1212a上还开设有第一螺钉孔12121a、第二螺钉孔12122a、第三螺钉孔12123a，三者两两相连呈三角状。盒体1a的第二侧端12a上一体成型的设置有与第一螺钉孔12121a、第二螺钉孔12122a、第三螺钉孔12123a一一对应的螺钉柱123a，螺钉沿着第一方向D1分别穿过第一螺钉孔12121a、第二螺钉孔12122a、第三螺钉孔12123a***螺钉柱123a内从而将盖部1212a固定在盒体1a的第二侧端12a，进而使得支架121a也被固定在盒体1a的第二侧端12a。盖部1212a上还开有第三定位孔12124a，盒体1a的第二侧端12a上一体成型有沿着第一方向D1向左突出的第一定位柱124a，第一定位柱124a***第三定位孔12124a内，从而使得盖部1212a以及支架121a在装配时首先被第一定位柱124a和第三定位孔12124a定位，避免在安装螺钉时第一螺钉孔12121a、第二螺钉孔12122a、第三螺钉孔12123a与螺钉柱123a难以对齐。盖部1212a在第二方向D2上位于电接触面7a与显影辊131a之间。
盖部1212a上还一体成型有定位部1213a，定位部1213a从盖部1212a沿着第二方向D2向下一体成型的延伸而形成，在第二方向D2上定位部1213a位于盖部1212a与显影辊131a之间。
如图36所示，本实施例中第一轴承5a上未设置螺钉孔，因此第一轴承5a不通过螺钉固定到盒体1a上。盒体1a的第二侧端12a上一体成型有形状大小能够与第一轴承5a的边缘贴合的定位凸缘122a，使得定位凸缘122a包围第一轴承5a，从而使得第一轴承5a在第二方向D2以及第三方向D3上被定位，第一轴承5a上还设置有第三扣合部51a，盒体1a的第二侧端12a上设置有与第三扣合部51a配合的第三扣合配合部。第三扣合部51a一体成型的从第一轴承5a上沿着第一方向D1向右延伸，第三扣合配合部为通孔状，第三扣合部51a***第三扣合配合部内，从而在第一方向D1上对第一轴承5a产生定位效果。进一步的，定位部1213a在第一方向D1上的投影与第一轴承5a至少部分重合并且定位部1213a与第一轴承5a的左端面抵接，使得定位部1213a能够将第一轴承5a压紧在盒体1a的第二侧端12a，进一步的防止第一轴承5a在第一方向D1上向左从盒体1a的第二侧端12a脱落。在第一方向D1上第一轴承5a位于定位部1213a与盒体1a第二侧端12a之间。通过以上设计，使得第一轴承5a无需采用螺钉固定到盒体，减少了螺钉的使用，降低成本，简化装配工艺。
本实施例中还取消了第一校正部和第二校正部，从而简化显影盒的结构。
如图28所示，本实施例中还公开了一种第二轴承115a的具体结构，第二轴承115a安装在盒体1a的第一侧端11a，第二轴承115a上开设有供显影辊131a的辊轴1311a ***的第二显影孔1154a，供送粉辊132a***的第二送粉孔1155a，第二显影孔1154a和第二送粉孔1155a可旋转的支撑送粉辊132a和显影辊131a的右端，第二轴承115a可旋转的支撑送粉辊132a和显影辊131a的左端，从而使得显影辊131a和送粉辊132a左右两端均被可旋转的支撑，使得显影辊131a和送粉辊132a能够在盒体1a内旋转。第二轴承115a上开有第四定位孔1152a和第五定位孔1153a，盒体1a的第一侧端11a上一体成型有第二定位柱113a和第三定位柱114a，第二定位柱113a位于第三定位柱114a的上侧和前侧，且显影辊131a的旋转轴线位于第二定位柱113a和第三定位柱114a之间，第二定位柱113a***第四定位孔1152a内，第三定位柱114a***第五定位孔1153a内，第四定位孔1152a为圆孔，第五定位孔1153a为腰形孔，从而使得第二轴承115a安装时被第二定位柱113a和第三定位柱114a定位，同时由于第五定位孔1153a为腰形孔，因此可以避免由于制造公差导致的误差使得第五定位孔1153a与第三定位柱114a无法对齐***的问题。第二轴承115a上还一体成型有从第二轴承115a左端面向左延伸而形成的第一扣合部1151a和第二扣合部，盒体1a的第一侧端11a上设置有呈通孔状的第一扣合配合部和第二扣合配合部，第一扣合部1151a***第一扣合配合部中并与第一扣合配合部产生抵接，第二扣合部***第二扣合配合部中并与第二扣合配合部产生抵接，从而使得第二轴承115a在第一方向D1上被定位，防止第二轴承115a在第一方向D1上向右脱出，进一步的护盖111a装配在盒体1a的第一侧端11a后压紧在第二轴承115a上，进一步防止第二轴承115a向右脱出盒体1a。同时第一定位柱124a和第二定位柱113a在第二方向D2和第三方向D3上对第二轴承115a进行定位，使得第二轴承115a能够牢固的安装在盒体1a的第一侧端11a上。
盒体1a的第一侧端11a上一体成型有驱动支撑轴112a，驱动部可旋转的安装在驱动支撑轴112a上，驱动支撑轴112a与第二轴承115a间隔，从而避免由于第二轴承115a是装配到盒体1a上的，因此第二轴承115a可能相对盒体1a出现位移，因此若驱动支撑轴112a是一体成型在第二轴承115a上时，则驱动部4a可能相对盒体1a出现位移，导致驱动部上的动力接收部4a与图像形成装置内的动力输出轴难以对齐，从而影响动力的接收。
本实施例还公开了一种传动组件的具体结构，与实施例一的区别在于，惰轮44a仅具有一级齿轮，惰轮44a与驱动齿轮啮合再与搅拌齿轮45a啮合，从而简化传动组件的结构，有利于显影盒体1a积的小型化。
如图37所示，本实施例还公开了一种护盖111a的具体结构，送粉齿轮42a被护盖111a覆盖，即送粉齿轮42a不会被护盖111a暴露，从而避免送粉齿轮42a受到外部碰撞导致损坏。
如图32、图33、图36所示，本实施例还公开了一种电接收部的具体结构，本实施例中，显影辊131a的辊轴1311a的左端向左伸出第二导引件54a，从而使得当显影盒安装到鼓框架92中后，显影辊131a的辊轴1311a直接与鼓框架92内的电极抵接，使得显影辊131a的辊轴1311a作为电接收部接收鼓框架92上的电极传输的电能，从而使得辊轴1311a带电，进而使得显影辊131a带电，并且盒体1a的第二侧端12a还安装有由导电材料(本实施例为钢片，其他实施例中也可以选用导电树脂、铜片等材料)制成的导电件6a，导电件6a包括第一电接触部62a和第二电接触部63a以及一 体成型的与第一电接触部62a和第二电接触部63a连接的电连接部61a，第一电接触部62a与显影辊131a的辊轴1311a的圆周面抵接，第二电接触部63a呈圆环状并且套设在送粉辊132a的左端且与送粉辊132a抵接并且电连接，电连接部61a上开设有第六定位孔611a，第一轴承5a朝向盒体1a第二侧端12a的一面上一体成型有向右突出的第四定位柱52a，第四定位柱52a***第六定位孔611a内，从而对导电件6a在第二方向D2和第三方向D3上进行定位，第二电接触部63a上还一体成型有第七定位孔631a，第一轴承5a朝向盒体1a第二侧端12a的一面上一体成型有向右突出的第五定位柱53a，第五定位柱53a***第七定位孔631a内，进一步对导电件6a在第二方向D2和第三方向D3上进行定位，第七定位孔631a和第六定位孔611a关于送粉辊132a的旋转轴线相对设置。本实施例中第一轴承5a为绝缘材料制成。当第一轴承5a安装到盒体1a的第二侧端12a上时，第一轴承5a将导电件6a压紧在盒体1a第二侧端12a与第一轴承5a之间，从而实现对第一轴承5a的在第一方向D1上的定位。导电件6a在第一方向D1上的投影与支撑部181a在第一方向D1上的投影不重合，导电件6a在第一方向D1上的投影与分隔壁183a在第一方向D1上的投影不重合，驱动部的旋转轴线不穿过导电件6a。从而使得导电件6a的体积最小化，节省空间，减少原材料成本，简化结构，并且能够稳定牢固的安装在盒体1a的第二侧端12a上。
第三种实施方式
本实施方式除特别说明的部分外，其他部分与第一种实施方式相同。
参照图38至图40所示，本实施方式中，第一种实施方式不同的是，第一受力块2141位于第一侧端11且直接设置在盒体10上，可以是与盒体10一体形成也可以是分体组装在盒体10上，第一斜面2142在第一方向D1上从左至右沿第三方向D3朝着靠近显影辊131的旋转轴线的方向延伸，进一步，第一斜面2142在第一方向D1上从左至右沿第三方向D3朝着靠近第六侧端16的方向延伸，即第一斜面2142的起始端21421比末端21422在第一方向D1上更靠近第二侧端12，且起始端21421比末端21422在第三方向D3上更远离第六侧端16。第一斜面2142用于接收分离力输出件91在第一方向D1上从右向左的分离力，以带动盒体10沿第三方向D3运动，使得显影辊131与感光鼓921脱离接触。
第四种实施方式
本实施方式除特别说明的部分外，其他部分与第一种实施方式相同。
参照图41至图44所示，本实施方式中，受力部包括包括第一受力块2141，第一受力块2141位于第一侧端11，第一受力块2141在第一方向D1上靠近分离输出件91的一侧设置有第一斜面2142，第一斜面2142受分离力输出件91抵接，本实施例中第一斜面2142优选为延伸方向平行于第二方向D2的直面，在其他实施例中可以是相对于第二方向D2倾斜的斜面。
分离件214还包括施力部，施力部用于与鼓框架92抵接，使得盒体10朝向远离感光鼓921的方向运动，施力部包括第一施力导向斜面2146，第一施力导向斜面2146沿第一方向D1从左至右在第三方向D3上朝着远离显影辊131的旋转轴线的方向延伸，进一步，第一施力导向斜面2146沿第一方向D1从左至右在第三方向D3上朝着远离第六侧端16的方向延伸，第一施力导向斜面2146的起始端比末端在第一方向 D1上更靠近第二侧端12，且起始端比末端在第三方向D3上更靠近第六侧端16，本实施例中第一施力导向斜面2146优选设置为两个，其一位于盒体10的第一侧端11，且位于第一间隔9233内，本实施例中优选第一施力导向斜面2146设置在第一受力块2141上，位于第一受力块2141在第一方向D1上背离分离输出件91的一侧，也可以是与第一斜面2142分体设置，另一第一施力导向斜面2146设置于盒体10的第二侧端12或者支架22上，且位于第二间隔9247内。
参照图4以及图42所示，鼓框架92内凹陷形成有方槽925，盒体10的支架22上设有第一支撑块26，第一支撑块26优选通过弹性件活动连接于盒体10上，或者滑动的设置在盒体10上，弹性件优选为弹簧27，第一支撑块26可相对于盒体10沿第一方向D1伸缩，第一支撑块26可延伸进方槽925内，以防止显影盒1相对于鼓框架92产生非预设的运动，在一些实施例中可以是第一支撑块26为弹性件。
位于第一侧端11的第一施力导向斜面2146用于与第一槽壁92331抵接，位于第二侧端12的第一施力导向斜面2146用于与突出部9243抵接，当位于第一侧端11的第一受力块2141接收到分离输出件91施加的从右至左的分离力时，分离力作用在设置于盒体10的第一侧端11的第一受力块2141上，第一受力块2141将分离力传递至盒体10的第二侧端12，即盒体10受到在第一方向D1上从右至左的推力，盒体10整体沿第一方向D1从右至左移动，位于第一侧端11的第一施力导向斜面2146与第一槽壁92331抵接，位于第二侧端12的第一施力导向斜面2146与突出部9243抵接，随着持续施加分离力，第一槽壁92331和突出部9243对第一施力导向斜面2146施加向后的反作用力，第一施力导向斜面2146将此分离力分解为一平行于第三方向D3的分离作用力，使得盒体10克服迫推力整体在第三方向D3上朝向远离感光鼓921的一侧移动，实现显影辊131与感光鼓921分离，与此同时，第一支撑块26被鼓框架92挤压并相对于盒体10运动，弹簧27积蓄弹性回复力。
可选的，可仅在第一侧端11或者第二侧端12处设置第一施力导向斜面2146，显影盒1接收分离力后，仅第一侧端11或者第二侧端12朝向远离感光鼓的方向运动。
当图像形成装置的分离力输出件91停止输出分离力时，盒体10在鼓框架92施加的迫推力和弹簧27的弹性回复力的作用下回位，显影辊131与感光鼓921重新接触。
第五种实施方式
本实施方式除特别说明的部分外，其他部分与第一种实施方式相同。
参照图45至图48所示，本实施方式中，与第一种实施方式不同的是，护盖21上设置有在第一方向D1延伸的支撑突起28，当显影装置处于安装到鼓框架92的状态下时，支撑突起28与位于第一间隔9233处的第一侧板923的上边缘抵接，从而被第一侧板923支撑，使得第一侧板923通过支撑突起28承受显影盒1的重力。
在第二方向D2上，显影辊131位于支撑突起28下方，第一受力块2141位于支撑突起28的上方，即支撑突起28位于显影辊131和第一受力块2141之间。在第二方向D2上第一受力块2141与支撑突起28对齐。在其他实施例中，第一受力块2141也可以位于支撑突起28的前侧或后侧。
护盖21上还设置有复位组件，复位组件包括弹性件和复位滑块29，弹性件优选 为弹簧27。护盖21上设置有安装槽，弹簧27安装在安装槽内，弹簧27可以在第三方向D3上拉伸或压缩，弹簧27前端与复位滑块29抵接，后端与安装槽后侧壁抵接，复位滑块29可沿第三方向D3移动的安装在安装槽内，安装槽的前侧壁上开有供复位滑块29伸出的通孔。复位滑块29位于第一受力块2141的前侧。
第一斜面2142在第一方向D1上从左至右沿第三方向D3朝着远离第六侧端16的方向延伸，即第一斜面2142的起始端比末端在第一方向D1上更靠近第二侧端12，且起始端21421比末端在第三方向D3上更靠近第六侧端16。第一斜面2142用于接收分离力输出件91提供的从右向左的分离力。
图像形成装置的分离力输出件91开始沿第一方向D1向左移动并开始抵接在第一受力块2141，第一斜面2142为延伸方向与第一方向D1倾斜的斜面，所以分离力输出件91可在第一方向D1上移动的过程中，抵接在第一斜面2142的不同位置，即分离力输出件91在第一斜面2142上相对于第一斜面2142从末端向起始端移动，第一斜面2142将此分离力分解为一平行于第三方向D3的作用力，并将该作用力传动至盒体10，使得盒体10以支撑突起28为枢转中心枢转，支撑突起28上方的盒体10向前摆动，支撑突起28下方的盒体10向后摆动，从而使得显影辊131随着盒体10一起向后摆动，即显影辊131朝向远离感光鼓321的方向摆动进而与感光鼓921脱离接触。可知的是，本实施例中第一斜面2142还可以是螺旋状。
本实施例中支撑突起28在第二方向D2上与第一受力块2141对齐使得第一斜面2142产生的向前的分离力作用点位于枢转中心的正上方，使盒体10枢转所需的力更小，更易使显影辊131与感光鼓921分离。
当显影辊131与感光鼓921分离时，复位滑块29与鼓框架92抵接并且挤压弹簧27，使得弹簧27产生弹性形变，当分离力撤销时，复位弹簧27的弹性形变则回复，使得复位滑块29对鼓框架92施加向前的推力，复位滑块29则受到向后的反作用力。从而推动支撑突起28上方的盒体10向后摆动，支撑突起28下方的盒体10则向前摆动，使得显影辊131向前摆动与感光鼓921接触。
实施例二
本实施方式除特别说明的部分外，其他部分与实施例一相同。
本实施例中，分离件214包括受力部、施力部以及传动部，受力部与施力部分别与传动部连接。
受力部用于接收图像形成装置提供的分离力，传动部可沿第一预设路径移动，以驱动施力部运动并抵接于鼓框架92，分离件214带动盒体10朝远离感光鼓921的方向运动，使得显影辊131与感光鼓921脱离接触。这样可以避免感光鼓921与显影辊131一直接触，感光鼓921将不需要的显影剂输送至图像形成装置内的转印带上污染转印带，同时也避免长时间的接触导致显影辊131或感光鼓921变形损坏。
第一种实施方式
参照图49至图51所示，本实施方式中，第一预设路径为传动部沿第一预设轴线为中心线的旋转移动路径，第一预设轴线沿第二方向D2延伸，施力部与受力部位于传动部的相对两侧。
受力部包括第一受力块2141，施力部包括第一施力块2144，第一受力块2141形 成有第一斜面2142，第一斜面2142的延伸方向相对于第一方向D1倾斜，第一斜面2142在第一方向D1上从左至右沿第三方向D3朝着靠近第六侧端16的方向延伸，即第一斜面2142的起始端21421比末端21422在第一方向D1上更靠近第二侧端12，且起始端21421比末端21422在第三方向D3上更远离第六侧端16。
传动部包括第一传动杆2143，第一受力块2141与第一施力块2144位于第一传动杆2143的第一方向D1相对两端，进一步为第一受力块2141位于第一传动杆2143在靠近第一侧端11的一侧，第一施力块2144位于另一端。在本实施方式中第一受力块2141、第一施力块2144和第一传动杆2143为一体成型结构，在其他实施方式中也可以是通过安装的方式固定在一起。在本实施方式中第一斜面2142可以为斜面，在其他实施方式中也可以是弧面。
在盒体10的表面凹陷设置有收容槽161，为第一传动杆2143的转动提供避让空间，收容槽161的轴线方向沿第一方向D1延伸，收容槽161内设有枢接轴162，第一预设轴线与枢接轴162的轴线相重合，均沿第二方向D2延伸，在枢接轴162上套设有如扭簧163等弹性回复件，第一传动杆2143的中部可转动的连接于枢接轴162上，扭簧163的一端与第一传动杆2143连接，扭簧163的另一端与盒体10连接，在常态下，扭簧163是自然伸展，在第一传动杆2143转动时候，扭簧163积蓄弹性回复力，在第一受力块2141失去受力后，扭簧163的弹性回复力释放，第一传动杆2143回到初始位置。
图像形成装置的分离力输出件91开始沿第一方向D1向左移动并开始抵接在第一受力导向斜面2142上，分离力输出件91在第一方向D1上移动的过程中，抵接在第一斜面2142的不同位置，即分离力输出件91在第一斜面2142上相对于第一斜面2142从末端21422向起始端21421移动。由于在第三方向D3上起始端21421比末端21422更靠近第六侧端16，同时第一斜面2142将此分离力分解为一平行于第三方向D3的作用力，此作用力推动第一传动杆2143绕枢接轴162转动，第一受力块2141向后摆动，第一施力块2144向前摆动并与鼓框架92上的突出部9243抵接，突出部9243对第一施力块2144施加向后的反作用力，反作用力通过第一传动杆2143施加到枢接轴162上，使得枢接轴162带动盒体10朝向远离感光鼓921的一侧移动，实现显影辊131与感光鼓921分离。
当图像形成装置的分离力输出件91停止输出分离力时，第一迫推部23施加的迫推力推动盒体10回位。同时扭簧163的弹性回复力释放，使得第一传动杆2143复位，盒体10向前移动至初始位置，显影辊131与感光鼓921恢复接触。在其他实施例中也可以不设置扭簧163。
第二种实施方式
参照图52所示，本实施方式中，第一预设路径为传动部沿第一预设轴线为中心线的旋转移动路径，第一预设轴线沿第三方向D3延伸，施力部与受力部位于传动部的相对两侧。
受力部包括第一受力块2141，第一受力块2141形成有第一斜面2142，第一斜面2142的延伸方向相对于第一方向D1倾斜，第一斜面2142的左端到右端在第二方向D2上与显影辊131的旋转轴线之间的距离逐渐增大，第一斜面2142的起始端21421 比末端21422在第一方向D1上更靠近第二侧端12，且起始端21421比末端21422在第二方向D2上更靠近显影辊131的旋转轴线。
传动部包括第一传动杆2143，第一受力块2141设置于第一传动杆2143的第一端，第一端位于第一侧端11，施力部形成于第一传动杆2143的第二端，第二端位于第二侧端12。
具体地，盒体10上设有枢接轴162，第一预设轴线与枢接轴162的轴线相重合，均沿第三方向D3延伸，第一传动杆2143的中部可转动的连接于枢接轴162上，第一受力块2141的一端与第一传动杆2143连接。
分离力输出件91提供沿第一方向D1的分离力，作用于第一受力块2141的第一斜面2142，第一斜面2142将此分离力分解为一平行于第二方向D2的分离作用力，此分离作用力推动第一传动杆2143绕枢接轴162转动，第一受力块2141向上(远离显影辊131旋转轴线)摆动，施力部与鼓框架92上的突出部9243抵接，第一传动杆2143继续受到向上的分力则使得枢接轴162受到向上的力，使得枢接轴162带动盒体10整体向上移动，盒体10则带动显影辊131在第二方向D2上向上移动而与感光鼓921分隔开。
可选的，不设置枢接轴162，第一受力块2141固定设置在第一侧端11，第一受力块2141接收分离力时，第一受力块2141带动盒体10的第一侧端11在第二方向D2上朝向远离感光鼓321的方向运动，显影辊131位于的一侧端11的一端与感光鼓321分离。
当撤销分离力时，在盒体10的自重作用下，盒体10向下掉落至显影辊131与感光鼓921接触的位置，或者增加复位弹性件为盒体10提供向下的弹力，使得盒体10向下移动而保证显影辊131与感光鼓921接触。
在本实施方式中，第一斜面2142受到向上的分力时，第一传动杆2143通过枢接轴162带动盒体10整体向上移动，在一些实施方式中，也可以不设置枢接轴162，第一斜面2142受到向上的分力时，第一传动杆2143通过抵接于护盖21或盒体10的其他位置而带动盒体10整体向上移动，此时，第一预设轴线可以是位于护盖21或盒体10的其他位置。在本实施方式中，施力部形成于第一传动杆2143的第二端，在一些实施方式中，施力部也可以形成于显影盒1的第二侧端12，只要第一传动杆2143带动显影盒1的第一侧端11向上运动时，显影盒1能绕着施力部转动，此时，第一预设轴线可以位于施力部。在本实施方式中，第一传动杆2143可转动的连接于枢接轴162，在一些实施方式中，第一传动杆2143也可以相对于盒体10固定。
第三种实施方式
参照图53至图59所示，本实施方式中，第一预设路径为传动部沿第一预设轴线为中心线的旋转移动路径，第一预设轴线沿第三方向D3延伸。
受力部包括第一受力块2141，第一受力块2141形成有第一斜面2142，第一斜面2142的左端到右端在第二方向D2上与显影辊131的旋转轴线之间的距离逐渐减小，即第一斜面2142的起始端21421比末端21422在第一方向D1上更靠近第二侧端12，且起始端21421比末端21422在第二方向D2上更远离显影辊131的旋转轴线。
传动部包括第一传动杆2143，第一受力块2141设置于第一传动杆2143的一端， 施力部包括第一施力块2144和第二施力块2145，第一施力块2144位于第一侧端11，优选与第一受力块2141连接，同时位于第一间隔9233内，第二施力块2145设置于第一传动杆2143的另一端并位于第二侧端12，同时位于第二间隔9247内，第一施力块2144与第二施力块2145均向第三方向D3延伸，第二施力块2145的端部形成有第一施力导向斜面2146，第一施力导向斜面2146的延伸方向相对于第一方向倾斜，进一步为第一施力导向斜面2146沿第三方向D3从上往下与显影辊131在第二方向D2上的距离逐渐增加。
请参阅图53、图55和图56，盒体10的第五侧端15设置第一安装部53、限位部168和第二安装部167。本实施例中第一安装部166沿第三方向D3凸出于盖体151，限位部168沿第三方向D3凸出于盖体151并沿第一方向D1延伸，第二安装部167沿第三方向D3凸出于盖体151，第一安装部166和第二安装部167为圆柱状，在第二方向D2上第二安装部167与限位部168至少部分重叠，在第二方向上限位部168比第二安装部167更远离显影辊131。
第一传动杆2143开设有固定通孔169，固定通孔169与第一安装部166匹配，第一传动杆2143通过固定通孔169安装至第一安装部166上而可拆卸地安装于盖体151上，第一传动杆2143可相对于盖体151运动，第一传动杆2143的中部可转动的连接于第一安装部166上，第一受力块2141的一端与第一传动杆2143连接，第一受力块2141的另一端形成有第一斜面2142。
第一传动杆2143在未受力发生运动时，第一传动杆2143的一部分在第二方向上受到盖体151下部的支撑，另一部分在第二方向D2上受限位部168和盒体10上设置的弹簧27的限位，防止第一传动杆2143产生非预设的摆动。在第一施力块2144向下转动过程中，第一传动杆2143向下压缩弹簧27，使得弹簧27积蓄弹性回复力。
图像形成装置上的分离力输出件91提供分离力，作用于第一受力块2141的第一斜面2142，第一斜面2142将此分离力分解为一平行于第二方向D2的分离作用力，此分离作用力将推动第一传动杆2143绕枢接轴162转动，使得第一受力块2141和第一施力块2144向下(靠近显影辊131的旋转轴线)摆动，第二施力块2145向上(远离显影辊131的旋转轴线)摆动。在第一施力块2144向下转动过程中，第一施力块2144上在第三方向D3上延伸的施力直面与鼓框架92上的第一槽壁92331抵接，具体抵接在第一槽壁92331在第三方向形成角度的斜面上，因此第一施力块2144在第三方向D3上向后移动，使得第一传动杆2143带动盒体10第一侧端11在第三方向上向后移动，在第二施力块2145向上转动过程中，第一施力导向斜面2146与鼓框架92上的突出部9243抵接，使得第一传动杆2143带动盒体10的第二侧端12在第三方向上向后移动，即第一槽壁92331和突出部9243分别对第一施力块2144和第二施力块2145施加向后的反作用力，使得盒体10整体朝向远离感光鼓921的一侧移动，实现显影辊131与感光鼓921分离。
当分离力消失时候，在弹簧27的弹力作用下，第一传动杆2143反转，第一施力块2144不再与第一槽壁92331和突出部9243抵接，第一迫推部23施加的迫推力推动盒体10回位，显影辊131与感光鼓921接触，分离件214也回到初始位置。
第四种实施方式
参照图60至图64所示，本实施方式中，受力部包括第一受力块2141，传动部包括第一传动块2147，施力部包括第一施力块2144，第一受力块2141与第一传动块2147的一端连接，第一施力块2144连接于第一传动块2147的另一端，且位于第一间隔9233内，第一受力块2141的背离第一传动块2147的一侧设有受力槽2148，在常态下，受力槽2148的延伸方向平行于第一方向D1。沿第一方向D1上，受力槽2148的靠近第六端的一侧形成受力面，盒体10上设有枢接轴162，第一预设轴线与枢接轴162的轴线相重合，均沿第二方向D2延伸，第一传动块2147的中部可转动的连接于枢接轴162上。
图像形成装置上的分离力输出件91提供分离力，作用于受力槽2148的受力面，受力槽2148将此分离力分解为一平行于第三方向D3的分离作用力，此分离作用力将盒体10推动第一传动块2147绕枢接轴162转动，第一施力块2144靠近第一槽壁92331，随着分离力持续施加，第一施力块2144与鼓框架92上的第一槽壁92331抵接，使得盒体10以显影辊131左端与感光鼓921左端接触的位置为枢轴点进行从显影辊131与感光鼓921完全抵接的位置进行枢转，使得显影辊131右端向后摆动从而移动到显影辊131与感光鼓921分离的位置。本实施方式中，定义左端为靠近第二侧端12的一端，右端为靠近第一侧端11的一端。
优选的是，在第一传动块2147上设有弹簧27等弹性回复件，在第一传动块2147发生旋转时候，弹簧27积蓄弹性回复力，当分离力消失时候，在弹簧27的弹力作用下，第一传动块2147反转，第一施力块2144不再与第一槽壁92331抵接，第一迫推部23施加的迫推力推动盒体10回位，显影辊131与感光鼓921接触，分离件214也回到初始位置。
实施例三
本实施方式除特别说明的部分外，其他部分与实施例一相同。
本实施例中，分离件214包括受力部、施力部以及传动部，施力部分别与传动部连接。
受力部用于接收图像形成装置提供的分离力，受力部可沿第二预设路径移动，传动部可沿第三预设路径移动，以使得施力部抵接于鼓框架92，分离件214带动盒体10朝向远离感光鼓921的方向运动，使得显影辊131与感光鼓921脱离接触。这样可以避免感光鼓921与显影辊131一直接触，感光鼓921将不需要的显影剂输送至图像形成装置内的转印带上污染转印带，同时也避免长时间的接触导致显影辊131或感光鼓921变形损坏。
第一种实施方式
参照图65至图67所示，本实施方式中，受力部包括第一受力杆2149以及第一受力块2141，第一受力块2141位于第一侧端11，第一受力杆2149沿第一方向D1延伸，施力部包括第一施力块2144，传动部包括第一传动杆2143以及第二传动杆2150。第二预设路径为受力部在第一方向D1上的线性移动路径，可以是平行于第一方向D1，也可以是在第一方向D1有位移，第三预设路径为传动部在第三方向D3上的线性移动路径，可以是平行于第三方向D3，也可以是在第三方向D3有位移，线性移动可以是直线型线性移动也可以是曲线型线性移动。具体地，第一受力块2141设置在第一 受力杆2149，且暴露在盒体10之外，以接收来自图像形成装置的分离力输出件91提供的分离力，第一受力块2141可增大与分离力输出件91的接触面积，提高受力部的移动稳定性。
第一传动杆2143的一端转动连接于第一受力杆2149上，第一传动杆2143的另一端与第二传动杆2150转动连接，第二传动杆2150与第一施力块2144连接。在盒体10上还可以设置导向结构164，以引导第二传动杆2150沿第三方向D3往复移动，第一受力杆2149在第一方向D1往复移动时候，带动第一传动杆2143转动，进而使得第二传动杆2150沿第三方向D3移动。

图像形成装置上的分离力输出件91提供沿第一方向D1的分离力，作用于第一受力块2141，第一受力块2141将此作用力传递至第一受力杆2149，第一受力杆2149沿第一方向D1由右向左移动，带动第一传动杆2143在由右向左移动的同时绕与第二方向D2平行的轴线转动，进而使得第二传动杆2150沿第三方向D3移动，位于第一间隔9233内的第一施力块2144与鼓框架92上的第一槽壁92331抵接，位于第二间隔9247内的第一施力块2144与鼓框架92上的突出部9243抵接，第一槽壁92331和突出部9243分别对第一施力块2144施加向后的反作用力，该反作用力朝向第三方向D3，反作用力通过第二传动杆2150、第一传动杆2143施加到第一受力杆2149上，使得盒体10整体朝向远离感光鼓921的一侧移动，实现显影辊131与感光鼓921分离。
优选的，在第一受力杆2149与盒体10之间还可以设置弹性复位件(图中未显示)，在第一受力杆2149被分离力输出件91提供沿第一方向D1的分离力带动从右向左移动时，弹性复位件被压缩，储存弹性力，弹性复位件释放弹性力使得第一受力杆2149在第一方向D1上从左向右运动以复位。
可选的，可仅在靠近第一侧端11或者第二侧端12处设置一个传动部和一个第一施力块2144，使得显影辊131在第一方向上的一端与感光鼓921分离。
当图像形成装置的分离力输出件91停止输出分离力时，第一迫推部23施加的迫推力推动盒体10回位，显影辊131与感光鼓921接触，分离件214也回到初始位置。

进一步地，传动部还设有第一传动杆2143，第一传动杆2143沿第一方向D1延伸，第一传动块2147设有两个，两个第一传动块2147设置于第一传动杆2143沿第一方向D1的相对两侧，其一位于第一间隔9233，另一位于第二间隔9247，每个第一传动块2147的外圆周面上均设有第一施力块2144，在第一施力块2144的底部设有凸柱2151，第一传动杆2143在第一方向D1的两侧均开设有孔，第一传动杆2143通过孔连接于凸柱2151上，在靠近第一侧端11的第一传动块2147的外圆周面上设有第一受力块2141，在第一受力块2141接收到分离力输出件91输出的分离力时候，第一传动块2147受力发生旋转，并带动第一传动杆2143沿第一方向D1从右往左移动，从而使得两个第一施力块2144同步转动，位于第一侧端11的第一施力块2144与第一槽壁92331抵接，第一槽壁92331给予位于第一侧端11的第一施力块2144反作用力，位于第二侧端12的第一施力块2144与突出部9243抵接，突出部9243给予位于第二侧端12的第一施力块2144反作用力，两个第一施力块2144将反作用力传递至盒体10，使得盒体10在第三方向D3上朝向远离感光鼓921的一侧移动，设置两个第一施力块可提高盒体10移动的稳定性和可靠性。
优选的是，在枢接轴162上套设有弹性件，弹性件优选为扭簧163，扭簧163与第一传动块2147连接，在第一传动块2147发生旋转时候，扭簧163积蓄弹性回复力，当分离力消失时候，在扭簧163的弹力作用下，第一施力块2144反转而不再与第一槽壁92331和突出部9243抵接，第一迫推部23施加的迫推力推动盒体10回位，显影辊131与感光鼓921接触，分离件214也回到初始位置。
第三种实施方式
参照图70以及图71所示，本实施方式中，受力部包括第一受力杆2149以及第一受力块2141，传动部包括第一传动缸体2152、第二传动缸体2153以及第一传动杆2143，第一传动缸体2152和第二传动缸体2153在第一方向D1上延伸且均具有在第三方向D3上的弯折部，其内填充有气体或者液体，第一传动缸体2152和第二传动缸体2153具备良好的密封性，第一传动杆2143优选为活塞，施力部包括第一施力块2144，第二预设路径为第一受力杆2149在第一方向D1上的线性移动路径，可以是与第一方向D1平行，也可以是在第一方向D1上具有位移，第三预设路径为第一传动杆2143在第三方向D3上的线性移动路径，可以是与第三方向D3平行，也可以是在第三方向D3上具有位移。本实施例优选设置有第一传动缸体2152和第二传动缸体2153，也可以仅设置一个传动缸体，可实现气体或者液体流通即可。
第一受力杆2149滑动安装于第一传动缸体2152内，第一受力块2141设于第一受力杆2149在第一方向D1上远离第二侧端12的一端，第一受力块2141用于接收图 像形成装置提供的分离力，第一受力杆2149沿第一方向D1延伸，第一受力杆2149和第一受力块2141优选为一体形成。
第二传动缸体2153与第一传动缸体2152相连通，第一传动杆2143滑动安装于第二传动缸体2153内，进一步为安装于第二传动缸体2153在第三方向D3上的弯折部处，第一施力块2144设于第一传动杆2143上，用于与第一槽壁92331抵接，第一传动杆2143沿第三方向D3延伸。
当第一受力块2141接收到图像形成装置施加的分离力时，第一受力块2141朝向第一传动缸体2152内部运动，气体或者液体在第一传动缸体2152和第二传动缸体2153内流动，使得第一传动缸体2152内压强增大，进而使得第二传动缸体2153内的压强也增大，由于第一传动缸体2152与第二传动缸体2153连通，从而使得第一施力块2144向前运动，第一施力块2144与第一槽壁92331抵接，第一槽壁92331随第一施力块施加反作用力，第一施力块2144将反作用力传递至盒体10第一侧端11(或者第二侧端12)，使得盒体10以显影辊131左端(或者右端)与感光鼓921左端(或者右端)接触的位置为枢轴点进行枢转，使得显影辊131右端(或者左端)向后摆动从而移动到显影辊131与感光鼓921分离的位置。
进一步地，第一施力块2144以及第一传动杆2143均设有两个，相应的，第二传动缸体2153具有两个在第三方向D3上的弯折部，第一受力块2141接收到分离力后，使得其一第一施力块2144与第一槽壁92331抵接，另一第一施力块2144与突出部9243抵接，两个第一施力块2144可以使得盒体10整体朝向远离感光鼓921的一侧移动，提高盒体10移动的稳定性和可靠性。
进一步地，第一受力杆2149上还套设有弹簧27等弹性回复件，弹簧27一端与第一传动缸体2152抵接，另一端与第一受力块2141抵接。当图像形成装置的分离力输出件91停止输出分离力时，同时弹簧27伸长而使得第一受力块2141沿第一方向D1从右往左运动以回到初始位置，使得第二传动缸体2153内的压强减小，从而使得第一施力块2144相对于盒体10向后运动，第一迫推部23施加的迫推力推动盒体10回位，显影辊131与感光鼓921重新接触。
进一步地，第一受力杆2149上可以不套设弹簧27，即，当图像形成装置的分离力输出件91停止输出分离力时，第一迫推部23施加的在第二方向D3上的迫推力使得盒体10在第二方向D3向靠近感光鼓321运动，此时，盒体10对于第一施力块2144施加作用力，第一施力块2144回复到第二传动缸体2153内，即第二传动缸体2153内的压强开始大于第一传动缸体2152，从而使得第一受力杆2149向右运动，显影辊131与感光鼓921重新接触，是否设置弹簧27在此不做具体限定。

当分离力输出件91对第一斜面2142施加沿第一方向D1的分离力时，第一斜面2142将此分离力分解为一平行于第二方向D2的作用力，从而驱动第一受力杆2149沿第二预设轴线为中心线的旋转移动路径旋转，即第一受力杆2149绕在第三方向D3上延伸的轴线摆动，进一步为第一斜面2142在第一方向D1的第一端向上摆动，第一受力块2141向下摆动，第一传动杆2143与第二斜面2154抵接，第二斜面2154给予第一传动杆2143一个第三方向D3的作用力，驱动第一传动杆2143沿第三方向D3移动，使得两个第一施力块2144分别与第一槽壁92331和突出部9243抵接，第一槽壁92331和突出部9243分别给予第一施力块2144一反作用力，两个第一施力块2144可以使得盒体10整体朝向远离感光鼓921的一侧移动，提高盒体10移动的稳定性和可靠性，实现显影辊131与感光鼓921分离。同时在第一传动杆沿第三方向D3移动时，弹簧27被压缩积蓄弹性回复力。
当图像形成装置的分离力输出件91停止输出分离力时，弹簧27的弹性回复力释放，使得第一传动杆2143和第一受力杆2149复位，第一迫推部23施加的迫推力推动盒体10回位，盒体10整体向前移动至初始位置，显影辊131与感光鼓921恢复接触。也可以不设置弹簧27，仅靠迫推力使得盒体复位。

图像形成装置上的分离力输出件91提供分离力，作用于第一分离杆体2157和第二分离杆体2158的转动连接处，使得第二分离杆体2158绕着与第一分离杆体2157的转动连接处发生转动，第二分离杆体2158的第二端与第一槽壁92331抵接，第一槽壁92331对第二分离杆体2158施加反作用力，第二分离杆体2158通过第一分离杆体2157将反作用力传递至盒体10的第一侧端11，使得盒体10的第一侧端11向后朝向远离感光鼓921的方向运动，进一步为盒体10以显影辊131左端与感光鼓921左端接触的位置为枢轴点进行枢转，盒体10的第一侧端11克服迫推力而向后摆动，使得显影辊131右端向后摆动，从而显影辊131移动到与感光鼓921分离的位置，即本实施例可使得显影辊131的右端与感光鼓921的右端脱离接触。本实施方式中，定义左端为靠近第二侧端12的一端，右端为靠近第一侧端11的一端。
进一步地，在第二分离杆体2158与第一侧端11之间还设有弹簧27等弹性回复件，在第二分离杆体2158发生转动时候，弹簧27被拉伸，积蓄弹性回复力，当图像形成装置的分离力输出件91停止输出分离力时，弹簧27的弹性回复力释放，使得第二分离杆体2158回到初始位置，第一迫推部23施加的迫推力推动盒体10回位，显影辊131与感光鼓921接触。
实施例六
本实施方式除特别说明的部分外，其他部分与实施例一相同。
参照图85至86所示，本实施例中，第一校正部215内设有支撑槽2160，在盒体10安装至鼓框架92时候，图像形成装置的分离力输出件91延伸进支撑槽2160内，分离力输出件91可以是沿着第一方向D1弹性设置的，这样在盒体10沿第二方向D2安装过程中，分离力输出件91可以产生弹性形变，进而避免分离力输出件91与第一校正部215干涉而刚性接触碰撞而损坏。
当分离力输出件91进入第一校正部215内后，不再第一校正部215的前侧壁挤压，因此在复位弹性件的弹力作用下分离力输出件91向左移动而复位并***第一校正部215的支撑槽2160内，而后当图像形成装置接收到分离指令时，分离力输出件91则向上(第二方向D2)移动，使得支撑槽2160的上侧壁接收到分离力输出件91施加的向上的力而被向上抬起。由于第一校正部215设置在护盖21上，因此护盖21带动盒体10一起向上移动，从而使得盒体10带动显影辊131向上移动，使得显影辊131与感光鼓921分离。
当图像形成装置不再接收到分离指令时，分离力输出件91向下移动，此时在显影装置自身的重力作用下，显影装置向下移动，使得显影辊131与感光鼓921再次抵紧接触。从而实现对显影辊131与感光鼓921的分离和接触。避免显影辊131与感光鼓921一直接触，导致不符合颜色需求的显影剂被输送到感光鼓921上。
本实施例中，识别组件上设有第一引导柱226以及第二引导柱227，识别组件可设置在第一侧端11或第二侧端12上，在第一侧端11或第二侧端12上设有引导板228，引导板228与第一侧端11或第二侧端12之间形成容纳空间，识别组件被收容于此容纳空间内，在引导板228上设有第一通槽229，护盖21或第二盖体上设有第二通槽230，第一引导柱226设于第一通槽229内，第二引导柱227设于第二通槽230内。使得识别组件相对于鼓框架92被定位即当显影装置被分离力输出件91驱动而向上移动时，识别组件不会随着盒体10一起移动，从而避免电接触端子与识别端子之间产生相对移动导致接触不良。可选的，识别组件还可以设置在盒体10的第一侧端11。
以上依据图式所示的实施例详细说明了本发明的构造、特征及作用效果，以上所述仅为本发明的较佳实施例，但本发明不以图面所示限定实施范围，凡是依照本发明的构想所作的改变，或修改为等同变化的等效实施例，仍未超出说明书与图示所涵盖的精神时，均应在本发明的保护范围内。
