PROBLEM TO BE SOLVED: To enable a photoreceptor and other parts for image recording to be attached/detached to/from the front surface side of an image forming device, and to easily perform the positioning of the photoreceptor to an electrostatic latent image forming device with high precision. SOLUTION: The image forming device is equipped with a plurality of photoreceptor units Uy-Uk mounted with a front end bearing BF and a rear end bearing BR, a rear plate PR having a plurality of rear end bearing supporting holes 5 which are positioned and fixed to an optical system support case CS 1 of a ROS and support the rear end bearing, a front plate PF which is positioned and fixed to the optical system support case CS 1 and has a parts attachment and detachment hole, and a positioning plate PH attachable/ detachable to/from the front plate PF and having a plurality of front end bearing positioning holes 13 which support the front end bearing BF. In the image forming device, the positioning of the bearing is performed on the inner side edge of the rear end bearing support hole 5 and the front end bearing positioning hole 13. |
