본 고안은 전자사진 프로세서의 현상기 토너 공급 장치The present invention is a developer toner supply device of an electrophotographic processor
Description
본 고안은 전자사진 프로세서에 관한 것으로서, 특히 토너적재부에서 토너가 현상롤러에 이송되기 전에 일정량이 쌓여있게 하는 돌출부가 형성된 프레임으로 구성되어 있는 토너 공급 장치에 관한 것이다.The present invention relates to an electrophotographic processor, and more particularly, to a toner supply apparatus which is composed of a frame having protrusions that allow a predetermined amount to accumulate before toner is transferred to a developing roller in a toner loading portion.
통상적으로 사용되는 전자사진 프로세서의 화상 형성 장치를 도 1을 참조하여 일반적인 인쇄공정을 설명하면 다음과 같다.A general printing process will be described with reference to FIG. 1 for an image forming apparatus of a conventionally used electrophotographic processor.
대전롤러(62)의 코로나 방전에 의해 감광드럼(60)의 표면을 전기적으로 균일하게 대전하고, 상기 감광드럼(60)의 회전에 의해 대전된 부분은 노광부(64)를 통해 화상을 형성하기 위한 전기적 신호를 받아 상기 감광드럼(60) 표면을 노광시키면 초기 대전된 상태에서 빛을 받은 부분은 정전잠상이 형성된다.The surface of the photosensitive drum 60 is electrically uniformly charged by the corona discharge of the charging roller 62, and the portion charged by the rotation of the photosensitive drum 60 forms an image through the exposure unit 64. When the surface of the photosensitive drum 60 is exposed by receiving an electrical signal, an electrostatic latent image is formed in a portion that receives light in an initial charged state.
이때, 토너는 교반기에 의해 일정 전하를 가지도록 교반되어져 현상롤러(68)측으로 이동되어 진다. 그후 상기 현상롤러(68) 표면에는 토너층이 형성되는데, 이때 상기 토너층은 독터블레이드의 규제에 의해 균일한 높이로 현상롤러(68) 표면에 형성되어 진다.At this time, the toner is stirred to have a constant charge by the stirrer and moved to the developing roller 68 side. Thereafter, a toner layer is formed on the surface of the developing roller 68. At this time, the toner layer is formed on the surface of the developing roller 68 at a uniform height by regulation of doctor blades.
그후, 상기 감광드럼(60) 표면에 형성된 정전잠상은 현상롤러(68)를 지나는 동안 토너로 현상되어 가시상으로 변하게 되고, 이어서 카세트(76)에 장착된 기록용지(78)가 급지롤러(80)에 의해 급지되며, 그후 상기 기록용기(78) 표면에는 전사롤러(74)의 고압 작용으로 상기 감광드럼(60) 표면의 토너 화상이 전사된다. 그후, 상기 기록용지(78)는 정착부의 히팅롤러(84)와 압축롤러(82) 사이를 통과하면서 열과 압력에 의해 기록용지(78) 표면에 상(image)이 정착되어져 받침대(86)측으로 이송되어 원하는 인쇄가 이루어진다.Thereafter, the electrostatic latent image formed on the surface of the photosensitive drum 60 is developed with toner while passing through the developing roller 68 to become a visible image, and then the recording paper 78 mounted on the cassette 76 is fed to the paper feed roller 80. Then, the toner image on the surface of the photosensitive drum 60 is transferred to the surface of the recording container 78 by the high pressure action of the transfer roller 74. Thereafter, the recording paper 78 passes between the heating roller 84 and the compression roller 82 of the fixing unit, and an image is fixed to the surface of the recording paper 78 by heat and pressure, and is transferred to the base 86 side. The desired printing is achieved.
한편, 전사롤러(74)를 지난 후의 감광드럼(60) 표면에 잔류하는 토너는 청소기(88)에 의해 제거되어 진다.On the other hand, the toner remaining on the surface of the photosensitive drum 60 after passing the transfer roller 74 is removed by the cleaner 88.
종래의 현상기는 도 2에 도시된 현상기의 단면도와 같이 나타난다.The conventional developer is shown as a cross-sectional view of the developer shown in FIG.
상기 현상기(66)에는 토너(44)를 저장하는 토너적재부(42)가 형성되며, 상기 토너적재부(42)의 중심부에는 토너(44)를 전기적으로 균일하게 교반시키는 교반기(46)가 설치되며, 토너(44)를 현상시키는 현상롤러(68) 높이로 균일하게 규제하는 독터블레이드(52)가 현상기 프레임에 설치된 것이다.The developing unit 66 is formed with a toner loading portion 42 for storing the toner 44, and a stirrer 46 for electrically and uniformly stirring the toner 44 is installed at the center of the toner loading portion 42. Then, the doctor blade 52 which is uniformly regulated to the height of the developing roller 68 for developing the toner 44 is provided in the developer frame.
상기와 같이 구성된 현상기의 동작 상태를 설명하면 다음과 같다.Referring to the operating state of the developing device configured as described above are as follows.
상기 현상기(66)의 일측면에 형성된 토너적재부(42)에 토너(44)가 공급되어지면, 상기 토너(44)는 교반기(46)에 교반되어지는 과정에서 마찰에 의한 정전기를 발생하게 되어 일정 전하를 가지게 된다. 그후, 상기 교반된 토너(44)는 처음 현상기(66) 제작시에 형성된 오픈갭(A)에 의해 토너적재부(42)에 적재된 토너(44)의 량(많고 적음)에 관계없이 현상롤러(68)측으로 이송되어진다. 그후, 상기 현상롤러(68) 표면에 형성된 토너(44)는 독터블레이드(52)에 의해 일정한 높이로 균일하게 규제되어 진다. 그후 도 1에 도시된 바와 같이 동작되어져 인쇄과정이 이루어진다.When the toner 44 is supplied to the toner loading part 42 formed on one side of the developer 66, the toner 44 generates static electricity by friction in the process of being stirred by the stirrer 46. It will have a constant charge. Thereafter, the stirred toner 44 is a developing roller regardless of the amount (more or less) of the toner 44 loaded in the toner loading part 42 by the open gap A formed when the developer 66 is first manufactured. It is conveyed to (68) side. Thereafter, the toner 44 formed on the surface of the developing roller 68 is uniformly regulated to a constant height by the doctor blade 52. It is then operated as shown in Figure 1 to perform the printing process.
그러나 위와 같은 방법을 사용할 때 토너적재부에서 현상롤러로의 공급량은 처음 제작되는 현상기 프레임의 형상에 의해 오픈갭(A)이 정해지고, 또한 교반기의 형상에 따라 공급부분의 공급량이 정해지지 때문에 상기 토너적재부에서 현상롤러측으로 이송되는 토너 공급량은 조절될 수 없으며, 따라서 현상롤러측으로 공급되는 토너량이 불균일(즉, 과잉공급현상 또는 공급부족 현상)하여 감광드럼 표면에 형성되는 토너 화상도 마찬가지로 불균일하게 형성되며, 이로인해 고해상도의 화상을 형성할 수 없는 문제점이 있었다.However, when using the above method, the supply amount from the toner loading portion to the developing roller is determined by the shape of the developer frame that is produced first, and the supply amount of the supply portion is determined by the shape of the agitator. The toner supply amount transferred from the stacking portion to the developing roller side cannot be adjusted, so that the toner image formed on the surface of the photosensitive drum due to unevenness of the toner supplied to the developing roller side (that is, oversupply or undersupply phenomenon) is also formed unevenly As a result, there is a problem in that a high resolution image cannot be formed.
상기와 같은 문제점을 해결하기 위하여 본 고안의 목적은 현상롤러에 토너를 균일하게 형성시키기 위하여 현상기의 토너 공급 장치를 제공하는데 있다.In order to solve the above problems, an object of the present invention is to provide a toner supply apparatus for a developer to uniformly form toner in a developing roller.
상기와 같은 목적을 달성하기 위하여 본 고안은 현상롤러와 토너가 접하는 방향의 앞쪽 프레임 하측에 토너를 임시로 쌓아놓을 수 있는 돌출부를 형성시켜 현상롤러에 균일하게 토너가 접하도록 하여 프린팅시, 균일한 화상을 얻음을 특징으로 한다.In order to achieve the above object, the present invention forms a protrusion for temporarily stacking the toner at the lower side of the front frame in the direction in which the developing roller and the toner are in contact with each other so that the toner is uniformly in contact with the developing roller. It is characterized by obtaining an image.

본 고안은 도 3에 도시된 바와 같이, 현상기(66)에는 토너(44)를 저장하는 토너적재부(42)가 형성되며, 상기 토너적재부(42)의 중심부에는 토너(44)를 전기적으로 균일하게 교반시키는 교반기(46)가 설치되며, 토너(44)를 현상시키는 현상롤러(68) 높이로 균일하게 규제하는 독터블레이드(52)가 현상기(66) 프레임에 설치되어 있다. 또한 현상롤러(68)와 토너(44)가 접하는 방향의 앞쪽 프레임 하측에 토너(44)를 임시로 쌓아놓을 수 있는 본 고안인 돌출부(20)를 형성시켜 현상롤러(68)에 균일하게 토너(44)가 형성되도록 한다.In the present invention, as shown in FIG. 3, a toner loading portion 42 for storing the toner 44 is formed in the developer 66, and the toner 44 is electrically formed at the center of the toner loading portion 42. An agitator 46 for uniformly stirring is provided, and a doctor blade 52 for uniformly regulating the height of the developing roller 68 for developing the toner 44 is provided in the frame of the developer 66. In addition, by forming the protrusion 20 of the present invention for temporarily stacking the toner 44 under the front frame in the direction in which the developing roller 68 and the toner 44 are in contact with each other, the toner 44 is uniformly formed on the developing roller 68. 44) is formed.
본 고안의 주요 작용은 상기 현상기(66)의 일측면에 형성된 토너적재부(42)에 토너(44)가 공급되어지면, 상기 토너(44)는 교반기(46)에 교반되어지는 과정에서 마찰에 의한 정전기를 발생하게 되어 일정 전하를 가지게 된다. 그후, 상기 교반된 토너(44)는 처음 현상기(66) 제작시에 형성된 오픈갭(A)에 의해 토너적재부(42)에 적재된 토너(44)의 량(많고 적음)에 관계없이 현상롤러(68)측으로 이송되어진다. 그후, 상기 현상롤러(68)의 앞쪽에 형성되어 있는 본 고안인 돌출부(20)에 상기 이송되어진 토너(44)가 적당량으로 쌓여서 현상롤러(68)에 균일하게 형성되며, 또한 상기 균일하게 형성된 토너(44)는 독터블레이드(52)에 의해 일정한 높이로 균일하게 규제되어 진다.The main action of the present invention is that when the toner 44 is supplied to the toner loading portion 42 formed on one side of the developer 66, the toner 44 is subjected to friction in the process of being stirred by the stirrer 46. The static electricity is generated and thus has a constant charge. Thereafter, the stirred toner 44 is a developing roller regardless of the amount (more or less) of the toner 44 loaded in the toner loading part 42 by the open gap A formed when the developer 66 is first manufactured. It is conveyed to (68) side. Thereafter, the transferred toner 44 is piled up in an appropriate amount on the protrusion 20 of the present invention, which is formed in front of the developing roller 68, and uniformly formed on the developing roller 68, and the uniformly formed toner. 44 is uniformly regulated to a constant height by the doctor blade 52.
상기 돌출부(20)는 현상롤러(68)와 토너(44)가 접하는 방향의 앞쪽 프레임 하측에 형성되며, 삼각형 모양으로 형성시킨다.The protrusion 20 is formed below the front frame in the direction in which the developing roller 68 and the toner 44 come into contact with each other, and are formed in a triangular shape.
상술한 바와 같이 본 고안의 실시예에 따른 현상기의 토너 공급 장치는 토너가 현상롤러에 균일하게 형성되기 때문에 이에따른 감광드럼 표면에 형성되는 토너화상도 마찬가지로 균일하게 형성되어 용지의 프린팅시 고해상도의 화상을 얻을 수 있는 효과가 있다.As described above, in the toner supply apparatus of the developing apparatus according to the embodiment of the present invention, since the toner is uniformly formed on the developing roller, the toner image formed on the surface of the photosensitive drum is also uniformly formed so that a high resolution image is printed when printing the paper. There is an effect that can be obtained.
