Description
본 고안은 프린터기의 토너 카트리지에 관한 것으로서, 특히 대전롤러에 크리닝수단이 구비됨으로써 전압강하가 방지되고, 대전롤러 표면이 깨끗한 상태로 유지되어 감광드럼에 잔존하는 잠상 폐토너의 전도가 원활하게 이루어짐으로 중복화상이 방지되어 선명한 고화질 화상을 얻도록 하는 한편, 설치공수가 추가되지 않고 세척이 간편하여 관리가 용이하도록 하는 프린터용 토너 카트리지에 관한 것이다.The present invention relates to a toner cartridge of a printer. In particular, the cleaning roller is provided with a cleaning means to prevent a voltage drop, and the surface of the charging roller is kept clean so that the latent image waste toner remaining in the photosensitive drum is smoothly conducted. The present invention relates to a toner cartridge for a printer which prevents overlapping images so as to obtain a clear, high-quality image, while facilitating management by not adding installation labor and facilitating cleaning.
일반적으로 프린터기에 장착되는 토너 카트리지(100)의 구성은 도 1에 도시된 바와 같이, 일정한 주속으로 회전되는 감광드럼(111), 상기 감광드럼(111)을 고전압으로 대전시키기 위해 감광드럼의 일측에 배치되는 대전롤러(113), 노광부(3)에 의하여 감광드럼(111)에 형성된 정전잠상 부분에 토너를 부착시키기 위하여 토너챔버(120)의 출구에 배치되는 현상롤러(115), 상기 감광드럼(111)의 다른 일측에 설치되어 급지된 용지(2)에 화상을 전사하기 위한 전사롤러(117), 감광드럼(111)에 잔존하는 폐토너를 감광드럼(111)으로부터 폐토너챔버(140)로 탈거시키기 위한 와이퍼 블레이드(130)로 대별할 수 있다.In general, the configuration of the toner cartridge 100 mounted on the printer is shown in Figure 1, the photosensitive drum 111 rotated at a constant circumferential speed, on one side of the photosensitive drum to charge the photosensitive drum 111 at a high voltage The developing roller 115 disposed at the outlet of the toner chamber 120 in order to attach the toner to the electrostatic latent image portion formed in the photosensitive drum 111 by the charging roller 113 and the exposure unit 3, and the photosensitive drum. The transfer roller 117 for transferring the image to the paper 2 loaded on the other side of the 111, and the waste toner remaining in the photosensitive drum 111 from the photosensitive drum 111 to the waste toner chamber 140. It can be roughly divided into the wiper blade 130 for removing.
이와 같은 구성의 종래기술의 토너 카트리지(100)의 작동과정을 살펴보면 다음과 같다.Looking at the operation of the conventional toner cartridge 100 of such a configuration as follows.
프린트 명령신호가 입력되면 감광드럼(111)을 비롯한 상기 모든 드럼들이 구동되면서 대전롤러(113)에 의하여 감광드럼(111)이 대전된다.(감광드럼 대전단계),When the print command signal is input, all the drums including the photosensitive drum 111 are driven and the photosensitive drum 111 is charged by the charging roller 113 (photosensitive drum charging step).
이렇게 대전된 감광드럼(111)에 별도 설치된 노광부(3)로부터의 노광에 의하여 정전잠상이 형성(정전잠상 형성단계)되고, 정전잠상이 형성된 감광드럼(111)에 토너챔버(20)의 입구에 설치된 현상롤러(115)가 토너를 도포한다(토너도포 단계).The electrostatic latent image is formed (electrostatic latent image forming step) by the exposure from the exposure unit 3 separately installed in the photosensitive drum 111 charged as described above, and the entrance of the toner chamber 20 to the photosensitive drum 111 having the electrostatic latent image formed thereon. The developing roller 115 installed thereon applies toner (toner coating step).
그리고, 토너가 도포된 감광드럼(111)과 전사롤러(117) 사이에 용지(2)가 급지되는 동시에 전사롤러(117)에 의하여 용지에 화상이 전사된다(전사단계).Then, the paper 2 is fed between the photosensitive drum 111 to which the toner is applied and the transfer roller 117, and the image is transferred to the paper by the transfer roller 117 (transfer step).
화상이 전사된 용지(2)는 별도로 설치된 두 개의 히터롤러(4) 사이를 통과하면서 토너가 용지에 정착되어(정착 단계) 프린트가 완료된다.The paper 2 on which the image has been transferred is passed between two heater rollers 4 separately installed, and the toner is fixed to the paper (fixing step) to complete printing.
한편, 전사단계를 거친 감광드럼(111)에는 잠상 폐토너가 잔존하고 있으며 와이퍼 블레이드(130)가 이 폐토너를 탈거시킨다(폐토너 크리닝 단계).On the other hand, latent waste toner remains in the photosensitive drum 111 which has undergone the transfer step, and the wiper blade 130 removes the waste toner (waste toner cleaning step).
상기 와이퍼 블레이드(130)는 유연성을 갖는 실리콘재로 된 블레이드(131)가 감광드럼(111)에 밀착되도록 설치되며, 이를 위하여 그 고정프레임(133)의 소정위치에는 하중압이 작용되도록 중량대(135)가 부여된다.The wiper blade 130 is installed so that the blade 131 made of a flexible silicone material is in close contact with the photosensitive drum 111, and for this purpose, a weight band is applied to a predetermined position of the fixing frame 133 to apply a load pressure. 135).
그러나, 상기 감광드럼(111)에는 와이퍼 블레이드(130)를 거친 뒤에도 잠상 폐토너가 완전히 제거되지 않으며, 이를 제거하기 위한 것이 상기 대전롤러(113)이다.However, the latent image waste toner is not completely removed from the photosensitive drum 111 even after passing through the wiper blade 130, and the charging roller 113 is used to remove the latent image waste toner.
상기 대전롤러(Primary Change Roller: PCR)(113)는 감광드럼(111)에 강한 음전하를 부여하여 감광드럼(111)을 대전시킴과 동시에 상기와 같이 감광드럼 상에 잔존하는 잠상 폐토너를 전도 흡착함으로써 선명한 화상을 얻도록 한다.The primary change roller (PCR) 113 imparts strong negative charge to the photosensitive drum 111 to charge the photosensitive drum 111 and at the same time conducts and adsorbs the latent image waste toner remaining on the photosensitive drum as described above. By doing so, a clear image can be obtained.
그러나, 종래 기술은 상기 대전롤러(113)에 크리닝 수단이 결여됨으로써 잠상토너가 증착 누적되어 프린팅 품질을 저하시키는 심각한 문제점이 있었다.However, the prior art has a serious problem that the latent image toner is deposited and accumulated by the lack of cleaning means in the charging roller 113, thereby reducing the printing quality.
즉, 와이퍼 블레이드(130)를 통하여 폐토너 크리닝 단계를 거치고 난 후에도감광드럼(111)에 잔존하는 잠상 폐토너가 대전롤러(113)에 증착되어 그 표면에 폐토너막이 형성됨으로써 대전전압이 떨어지고, 이에 따라 감광드럼(111)의 정전잠상 형성이 흐려짐으로 프린트 품질을 저하시키게 된다.That is, even after the waste toner cleaning step through the wiper blade 130, the latent image waste toner remaining on the photosensitive drum 111 is deposited on the charging roller 113 to form a waste toner film on the surface thereof, thereby reducing charging voltage. Accordingly, the electrostatic latent image formation of the photosensitive drum 111 is clouded, thereby degrading the print quality.
또한, 이와 같이 대전롤러의 표면에 증착형성되는 폐토너로 인하여 감광드럼에 잔존하는 잠상 폐토너가 제거되지 못하고 다음 차례의 정전잠상과 중복되어 프린팅 품질을 저하시키는 문제점이 있었다.In addition, due to the waste toner deposited on the surface of the charging roller, the latent latent waste toner remaining in the photosensitive drum cannot be removed, and thus the printing quality is overlapped with the next electrostatic latent image.
본 고안은 상기한 문제점을 해소하기 위하여 안출된 것으로서,The present invention has been devised to solve the above problems,
본 고안의 목적은, 대전롤러에 크리닝수단이 구비됨으로써 전압강하가 방지되고, 대전롤러 표면이 깨끗한 상태로 유지되어 감광드럼에 남아있는 잠상 폐토너의 전도가 원활하게 이루어짐으로 중복화상이 방지되어 깨끗하고 선명한 화상을 얻도록 하는 프린터용 토너 카트리지를 제공함에 있다.The object of the present invention is to provide a cleaning means to the charging roller to prevent voltage drop, and the surface of the charging roller is kept in a clean state so that the latent image waste toner remaining on the photosensitive drum is smoothly conducted so that the overlapping image is prevented and clean. To provide a toner cartridge for a printer to obtain a clear and clear image.
본 고안의 다른 목적은 대전롤러 크리닝수단이 와이퍼 블레이드에 부설됨으로써 부품 및 설치공수가 추가되지 않고, 세척이 간편하여 관리가 용이하도록 하는 프린터용 토너 카트리지를 제공함에 있다.Another object of the present invention is to provide a toner cartridge for a printer, in which a charging roller cleaning means is attached to a wiper blade so that parts and installation labor are not added, and cleaning is easy and easy to manage.

도 2 및 도 3에 도시된 바와 같이, 본 고안에 따른 일 실시예의 프린터용 토너 카트리지는,As shown in Figure 2 and 3, the toner cartridge for a printer of one embodiment according to the present invention,
감광드럼(11), 상기 감광드럼(11)을 고전압으로 대전시키기 위해 감광드럼의일측에 배치되는 대전롤러(13), 상기 대전롤러(13)에 의해서 대전된 감광드럼(11)에 일정한 화상을 노광시키기 위해 별도설치되는 노광부(3)에 의하여 형성된 정전잠상 부분에 토너를 부착시키기 위하여 토너챔버(20)의 출구에 배치되는 현상롤러(15), 상기 감광드럼(11)의 다른 일측에 설치되어 급지된 용지(2)에 화상을 전사하기 위한 전사롤러(17), 상기 감광드럼(11)에 잔존하는 폐토너를 폐토너챔버(40)로 탈거시키기 위한 블레이드(31)와 고정프레임(33) 및 중량대(35)로 형성되는 와이퍼 블레이드(30)를 포함하여 구성되는 토너 카트리지에 있어서,A constant image is applied to the photosensitive drum 11, the charging roller 13 disposed on one side of the photosensitive drum to charge the photosensitive drum 11 at a high voltage, and the photosensitive drum 11 charged by the charging roller 13. A developing roller 15 disposed at the outlet of the toner chamber 20 and the other side of the photosensitive drum 11 to attach the toner to the electrostatic latent image portion formed by the exposure unit 3 separately provided for exposure. Transfer roller 17 for transferring the image onto the paper 2 to be fed, and the blade 31 and the fixing frame 33 for removing the waste toner remaining in the photosensitive drum 11 with the waste toner chamber 40. In the toner cartridge comprising a wiper blade 30 formed of a weight band 35),
상기 대전롤러(Primary Change Roller: PCR)(13)의 표면을 크리닝하기 위한 대전롤러 크리닝수단(50)이 구비되는 것이다.The charging roller cleaning means 50 for cleaning the surface of the primary change roller (PCR) 13 is provided.
상기 대전롤러 크리닝수단(50)은 상기 대전롤러(13)의 일측 표면에 말착되며, 와이퍼 블레이드(30)에 부설됨이 바람직하다.The charging roller cleaning means 50 is attached to one surface of the charging roller 13, it is preferable to be attached to the wiper blade (30).
