Abstract

본 발명은 화상 형성 장치에 관한 것이며, 카트리지의 착탈을 간단히 할 수 있고, 더구나, 소형화 경량화 및 비용 경감을 도모하는 것을 목적으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus, and an object of the present invention is to simplify attachment and detachment of a cartridge, and furthermore, an object thereof is to reduce the size, weight, and cost.

장치 본체에 착탈되는 드럼 카트리지(1)이 카트리지 본체(2)와 카트리지 본체(2)에 상담지체(3)의 축심 방향으로 슬라이드 가능하게 지지되는 샤프트(4)와 이 샤프트(4)를 슬라이드 방향의 한쪽으로 가압하는 스프링(11)를 구비하고, 상기 샤프트(4)를 상담지체(3)의 지름 방향 또는 이것에 평행인 방향으로부터 장치 본체의 카트리지 지지부에 끼워 넣음으로써 본체 위치 결정 수단과 스프링 에 의하여 카트리지의 장전시에 카트리지가 본체 장치내에서 위치 결정됨과 공시에 샤프트가 위치 결정되는 구성으로 한다.The shaft 4 and the shaft 4 in which the drum cartridge 1 detachably attached to the apparatus main body are slidably supported by the cartridge main body 2 and the cartridge main body 2 in the axial direction of the consultation body 3 are slid in the sliding direction. A spring 11 for pressing to one side of the body, and the shaft 4 is inserted into the cartridge support portion of the apparatus main body from the radial direction of the consultation body 3 or a direction parallel thereto. Thereby, the cartridge is positioned in the main body apparatus at the time of loading of the cartridge, and the shaft is positioned at the same time.
