A process unit positioning device, which performs mutual positioning of process units individually comprising photosensitive drums corresponding to different colors of toner with respect to an apparatus main body, comprising:
- a positioning plate in which bearing holes into which individual drum shafts of the respective photosensitive drums are fitted and a positioning portion onto which the apparatus main body is fitted are formed;
- a holder portion provided to the apparatus main body, for inserting/removing the drum shafts relatively into/from the bearing holes by being caused to pivot while holding the positioning plate;
- and
- an urging member for urging the positioning plate toward the drum shafts in an axial direction with respect to the holder portion,
- wherein the holder portion holds the positioning plate so that a position with respect to the holder portion changes against urging of the urging member by contact between the bearing holes and the drum shafts when the drum shafts are fitted into the bearing holes by the pivot.
