を特徴とする複写機の作像装置。 An image forming device for a copying machine in which a photosensitive drum unit and a developing unit are separately inserted and removed in the direction of the drum axis through an opening for insertion and removal of the units formed in the front side plate of the copying machine body and a support guide mechanism. , by moving in the direction of the drum axis a center-to-center dimension defining member that defines the center-to-center dimension on the opening side of the photosensitive drum axis of the photosensitive drum unit and the developing roller axis of the developing unit in a predetermined manner; A retaining fixing member is provided across both units in a state in which the connection with the developing unit is released, an operating handle is formed on the shaft dimension defining member, and the retaining member is fixed to the photosensitive drum unit frame. The developing unit is removably attached to the front plate of the copying machine main body in a state in which the developing unit can be extracted, and a spring is attached to the center-to-center dimension determining member to maintain a connected state of the center-to-center dimension determining member to the developing unit. A developing unit is interposed between the fixing member and the developing unit so that the developing unit can be inserted and removed by rotating the inter-axis dimension defining member by a predetermined angle while the urging connection is released against the urging force of the spring. An image forming device for a copying machine, characterized in that the photosensitive drum unit can be inserted and removed in a state where the fixing member is disconnected from the front side plate of the copying machine main body.
