Image Forming Apparatus

An image forming apparatus comprising:

• a plurality of photosensitive drums spaced apart from each other and arranged such that axes of the photosensitive drums are parallel relative to each other in an arrangement direction perpendicular to an axial direction of the photosensitive drums;
• a frame member configured to accommodate the photosensitive drums such that the photosensitive drums are withdrawn relative to the frame member along the axial direction;
• a first sheet metal member disposed on a first side of the frame member, the first sheet metal member being configured to position the photosensitive drums;
• and
• a pressing member configured to press the photosensitive drums toward the first sheet metal member,
• wherein the frame member includes:
• a first wall disposed on a second side, opposite to the first side in the axial direction, of the frame member;
• a second wall disposed on a third side of the frame member, the third side connecting the first side and the second side, the second wall being connected to the first wall;
• and
• a third wall disposed on an upper side relative to the photosensitive drums, the third wall being connected to the first wall and the second wall.
