PURPOSE:To obtain an image forming device in which a photosensitive unit and a developing unit which can be attached/detached are surely positioned. CONSTITUTION:In the developing unit 6, a developing sleeve driving gear 13 is set as a planet gear so that the gear 13 may abut on a gear 8 to be driven by the developing sleeve after inserting a supporting point 15 in a guide 11, and in the photosensitive unit 3, a guide 105 is such formed that a rotational center shaft 14 moves in a direction where it separates from the developing unit 6 as the shaft 14 is inserted in the guide 105. The supporting point 15 and the shaft 14 are made to easily get in the deep parts of the guides 11 and 105, respectively, so that they are positioned in the deepest parts of the guides 11 and 105. |
