PROBLEM TO BE SOLVED: To provide an image forming device capable of holding a press-contact member and a photoreceptor drum in a state where the press-contact member is not strongly pressed to the photoreceptor drum when a photoreceptor unit is single. SOLUTION: Bearings attached to both ends of the photoreceptor drum are fit in bearing fitting holes formed on the casing of the photoreceptor unit, and the bearing fitting hole is formed as a long hole so that the bearing can move within a specified range in a direction where the photoreceptor drum is pressed to the press-contact member and a direction where such pressing is released, and the bearing is held at a position where pressing the photoreceptor drum to the press-contact member is released when the photoreceptor unit is single. Then, a supporting member provided in an image forming device main body is equipped with a mechanism for moving and holding the bearing at a position where the photoreceptor drum is pressed to the press-contact member when the photoreceptor unit is attached to the supporting member. |
