For example, an electrostatic latent image is formed by scanning a laser beam on a charged photosensitive medium, and the electrostatic latent image is formed by toner particles. It uses a transfer photograph printing method which is developed as a visible image to transfer and fix on a printing paper.
이러한 화상형성기에 화상을 형성하는 현상장치의 한 예로서, 한국공개특허 제2003-38136호에 개시된 현상장치는 감광체의 표면을 일정전하로 대전시켜 주는 대전수단과, 렌즈를 통해 입사되는 노광에 의해 생성된 감광체의 전기적 잠상에 토너를 부착시켜주는 현상롤러와, 용지에 토너를 옮겨 부착시켜주는 전사롤러, 그리고 용지에 인쇄를 행하는 감광체로 형성되고, 현상롤러와 인접한 위치에 현상제를 수용하는 현상제통과, 현상제를 현상롤러로 공급하는 공급롤러가 마련되어 있다.As an example of a developing apparatus for forming an image in such an image forming apparatus, the developing apparatus disclosed in Korean Patent Laid-Open Publication No. 2003-38136 has a charging means for charging a surface of a photosensitive member with a constant charge, and an exposure incident through a lens. A developing roller for attaching toner to the latent electrical latent photosensitive member, a transfer roller for transferring toner to the paper, and a photosensitive member for printing on the paper, and containing the developer in a position adjacent to the developing roller. A supply roller for passing through the developer and supplying the developer to the developing roller is provided.
한편, 이러한 화상형상장치의 현상장치에서는 공급롤러에 의해 현상제통의 현상제가 현상롤러로 공급되고, 공급된 현상제는 현상롤러에 의해 감광체에 형성된 전정잠상영역에 부착되며, 감광체를 통과하는 인쇄용지로 옮겨짐으로써 인쇄가 이루어진다.On the other hand, in the developing apparatus of such an image forming apparatus, the developer in the developer container is supplied to the developing roller by a supply roller, and the supplied developer is attached to the vestibular latent image area formed on the photosensitive member by the developing roller and passes through the photosensitive member. Printing is done by moving to.
그런데 감광드럼에 현상된 토너 중 소량은 인쇄용지로 옮겨지지 못하고 잔류하게 되며, 이러한 잔류 폐토너는 클리닝수단에 의해 제거되어 폐토너 회수경로를 통해 폐토너회수통에 회수된다. However, a small amount of the toner developed on the photosensitive drum is not transferred to the printing paper and remains. The residual waste toner is removed by the cleaning means and collected in the waste toner collection container through the waste toner recovery path.

이러한 구성에 의해 본 발명에 따른 화상형성기의 작동과정을 살펴보면 다음과 같다. Looking at the operation of the image forming apparatus according to the present invention by such a configuration as follows.
우선 대전롤러에 의해 상담지체의 표면을 전기적으로 균일하게 대전시킨 후, 광유닛을 통해 상담지체 상에 정전잠상을 형성시킨다. 그리고, 현상제는 공급롤러에 의해 현상제이송체에 실려 현상제이송체의 회전에 의해 현상영역으로 이송된다. 이때, 현상제량규제부재에 의해 현상제이송체에 일정한 두께의 현상제층을 형성시키게 된다. 그런 후, 상담지체가 회전하여 현상영역을 지나면서 현상제를 끌어당겨 정전잠상에 붙임으로써 상담지체상에 가시상 형태의 현상제가 현상된다. 이때, 현상제이송체와 상담지체 사이에 소정 간격 이격된 현상영역으로 이송된 현상체가 상담지체에 형성된 정전잠상으로 이동되기 위해서는 전원공급부를 통하여 전압을 현상제이송체에 인가하게 된다. 그런 후, 급지부에 의해 용지를 전사롤러로 공급되면, 전사롤러에 인가된 고압 및 정전기력에 의해 상담지체에 부착된 현상제가 용지로 전사하게 된다. 그런 후, 용지로 전사된 현상제는 정착부의 열과 압력에 의해 용지에 정착된다. 이에 용지에 정착된 화상은 배지부를 거쳐 장치본체(10) 밖으로 배출됨으로써 인쇄를 완료하게 된다.First, the surface of the consultation body is electrically uniformly charged by the charging roller, and then an electrostatic latent image is formed on the consultation body through the optical unit. Then, the developer is loaded on the developer conveying body by the feed roller and transferred to the developing region by the rotation of the developer conveying body. At this time, a developer layer having a predetermined thickness is formed on the developer carrier by the developer amount regulating member. Thereafter, the counseling member rotates and pulls the developer while passing through the developing region and attaches the electrostatic latent image to develop the developer in the form of a visible image on the counseling member. At this time, in order to move the developer transferred to the developing region spaced a predetermined distance between the developer carrier and the counseling member to the electrostatic latent image formed on the counseling member, a voltage is applied to the developer carrier through the power supply unit. Then, when the paper is supplied to the transfer roller by the paper feeding unit, the developer attached to the consultation body is transferred to the paper by the high pressure and the electrostatic force applied to the transfer roller. Then, the developer transferred to the paper is fixed to the paper by the heat and pressure of the fixing unit. The image fixed to the paper is discharged out of the apparatus main body 10 through the discharge unit to complete printing.
한편, 상담지체에 현상된 현상제 중 소량은 인쇄용지로 옮겨지지 못하고 잔류하게 될 때, 이러한 잔류 현상제는 클리닝블레이드에 의해 제거되어 소정의 폐토너 회수경로를 통하여 최종적으로 폐현상제수용케이스(20)에 회수된다. 이 폐현상제수용케이스(20)는 장착부(11)에 장착된 상태로 폐현상제수용케이스(20)의 토출부삽입구(32)로 장착부(11)의 폐현상제토출부(12)가 삽입되어 있어 이 폐현상제토출부(12)를 통해 폐현상제가 폐현상제수용케이스(20)에 도달하게 되는것이다. On the other hand, when a small amount of the developer developed in the counseling member is not transferred to the printing paper and remains, the residual developer is removed by the cleaning blade and finally, through the predetermined waste toner recovery path, the waste developer accommodating case 20 ) Is recovered. The waste developer housing case 20 is mounted on the mounting unit 11 and the waste developer discharge unit 12 of the mounting unit 11 is inserted into the discharge unit insertion hole 32 of the waste developer housing case 20. Through the waste developer discharge unit 12, the waste developer reaches the waste developer accommodation case 20.
이때 폐현상제수용케이스(20)는 하부커버(30)의 결합홈(33)에 상부커버(40)의 걸림리브(41)가 수용되어 상부커버(40)와 하부커버(30)는 상호 결합된 상태이고, 여기서 연결부분(44)을 중심으로 양측에 배치된 보스(51)에 연장커버부(43)의 삽입돌기(52)가 소정의 높이(h)만큼의 단차를 실링하는 실링부(50)가 형성된 상태이기 때문에, 현상제수용케이스(20) 내부에 수용된 폐현상제는 외부로 유출되는 것이 방지될 수 있는 것이다.At this time, the waste developing case 20 has a locking rib 41 of the upper cover 40 is received in the coupling groove 33 of the lower cover 30 so that the upper cover 40 and the lower cover 30 are coupled to each other. In this case, the sealing portion 50 in which the insertion protrusion 52 of the extension cover portion 43 seals the step by a predetermined height h to the bosses 51 disposed on both sides of the connection portion 44. ) Is formed, the waste developer contained inside the developer accommodating case 20 can be prevented from leaking to the outside.
이상 설명한 바와 같이, 본 발명에 따르면, 상부커버와 하부커버의 결합영역의 기밀을 향상시켜 현상제수용부 외부로 현상제가 유출되는 것을 방지할 수 있는 있게 된다. As described above, according to the present invention, it is possible to prevent the developer from leaking out of the developer accommodating part by improving the airtightness of the coupling region of the upper cover and the lower cover.
