PROBLEM TO BE SOLVED: To facilitate work of attaching a module to be exchanged, arranged at a position opposed to a surface of a latent image carrier from above, to a unit frame body of an image forming unit.SOLUTION: A rear-side lower regulation part 133 and an inner wall of the upper surface of a positioning aperture 136 which hold a rear-side positioning member of an electrification module in between are arranged such that a holding position C1 of the inner wall of the upper surface is located on the outside in a rotary shaft direction of a photoreceptor from a holding position C2 of the rear-side lower regulation part 133, and the electrification module is set to a state (a) where the rear-side positioning member is inserted between the holding positions from obliquely above on the inside in the rotary shaft direction of the photoreceptor, and then a front-side positioning member of the electrification module can be placed on an upper surface of a positioning pedestal. |
