Abstract

복사기 또는 레이저 프린터와 같은 전자 사진 장치는 토너를 운송하기 위한 감광성 벨트(4)를 갖고 있다. 감광성 벨트(4)는 카트리지(2)에 장착되고, 카트리지는 홀더(11)에 제거 가능하게 장착된다. 홀더(11)은 장치의 주몸체(1)로부터 삽입 및 회수 가능하다. 따라서, 감광성 벨트(4)의 사용수명이 종료하게 될 때, 홀더(11)은 회수되고, 카트리지(2)는 제거된다. 새로운 카트리지(2)와 새로운 감광성 벨트(4)는 홀더(11)에 장착될 수 있고, 홀더(11)은 장치의 주 몸체(1)에 삽입된다. 카트리지(2) 및 홀더(11)은 공기 입구(11b) 및 공기 출구를 갖고 있다. 따라서, 공기가 홀더(11)의 대향 표면과 소정의 토너를 이송하는 카트리지(2) 사이로 흐르게 되고, 홀더(11)의 내부로부터 그러한 토너를 제거한다.An electrophotographic apparatus such as a copier or a laser printer has a photosensitive belt 4 for transporting toner. The photosensitive belt 4 is mounted to the cartridge 2, and the cartridge is detachably mounted to the holder 11. The holder 11 is insertable and withdrawable from the main body 1 of the device. Thus, when the service life of the photosensitive belt 4 ends, the holder 11 is recovered and the cartridge 2 is removed. A new cartridge 2 and a new photosensitive belt 4 can be mounted to the holder 11, which is inserted into the main body 1 of the device. The cartridge 2 and the holder 11 have an air inlet 11b and an air outlet. Thus, air flows between the opposing surface of the holder 11 and the cartridge 2 carrying the predetermined toner, and removes such toner from the inside of the holder 11.
