PROBLEM TO BE SOLVED: To provide an image forming device having a positioning mechanism for a photosensitive body in which an operating power required for attaching and detaching a holding plate holding one end of a shaft of a photosensitive body to a device body can be further lightened, and degradation of positioning accuracy due to repetition of attaching and detaching operation can be prevented. SOLUTION: A first positioning hole 42 is provided at a device body 4 and a second positioning hole 52 and a bearing hole 51 are provided at a holding body 5, the holding plate 5 is positioned at the device body 4 by inserting a positioning member 6 into both of the first and the second positioning holes until engaging simultaneously in a state in which a shaft 50 of a photosensitivity body 32 is inserted into the bearing hole 51 using the positioning member 6 having at least a positioning plane part coinciding with both of the first and the second positioning holes and being inserted and a taper plane part tilting to a tip side of the positioning plane part taperingly and a member 7 for inserting which inserts the positioning member 6 into the first and the second positioning holes. |
