PROBLEM TO BE SOLVED: To allow an inexpensive configuration to securely prevent a photoreceptor drum from being damaged upon loading the photoreceptor drum to a frame member of an electric charging member.SOLUTION: An image formation unit comprises: an electric charging member that extends in a rotation axis direction of a photoreceptor drum; and a holding member that holds the electric charging member to the frame member. In a state where the electric charging member is held to the frame member via the holding member, the electric charging member is disposed side by side with the photoreceptor drum by making mutual rotation axes parallel in a state in contact with a peripheral face of the photoreceptor drum, and the holding member and the frame member are provided at a tip end part of an attachment direction of the holding member in the holding member and at a reception position of the holding member in the frame member. The image formation unit has an interference preventive formation part that, when attaching the electric charging member to the frame member via the holding member, firstly comes into contact with the frame member to thereby allow interference between the holding member and the photoreceptor drum to be prevented.SELECTED DRAWING: Figure 5 |
