Abstract
An electrostatic copying apparatus including a support frame having a front support wall and a rear support frame. The support frame is mounted on a housing slidably in the front and rear direction between an operating position within the housing and a pull-out position outside of the housing. A rotating drum and a developing device are mounted on the support frame. Each of the rear surface of the front support wall and the front surface of the rear support wall has a semicircular receiving portion with an open top, and each end of the rotating drum has a shaft bearing member with a circular peripheral surface. By inserting each bearing member into the associated receiving portion, the drum is rotatably mounted. The developing device has a front wall and a rear wall, with a projecting portion formed at the end of each. An abutting lower edge is defined on each projecting portion, and an abutting front edge is defined on each of the front wall and the rear wall, below the projecting portion. The developing device is mounted between the front support wall and the rear support wall with each abutting lower edge abutting against the upper surface of the associated bearing member when that associated bearing member is inserted into its associated receiving portion and with each abutting front edge abutting against the side surface of the associated receiving portion.
