An image forming apparatus (100) includes a first pressing member (80) pressing a unit (39) having a second rotating member (25) contactable with a first rotating member (1), and a supporting member (31) rotatably supporting the second rotating member (25). The first pressing member (80) moves the supporting member (31) and the second rotating member (25) moves from the contact position to the separated position. Also provided is a second pressing member (106) that presses the supporting member (31). The second pressing member (106) can move between a mounting/detaching restriction position restricting mounting/detaching of the cartridge (9), and a mounting/detaching allowing position allowing mounting/detaching of the cartridge (9). The second pressing member (106) moves the unit (39) to a position distanced from the first rotating member (1) by moving from the mounting/detaching restriction position to the mounting/detaching allowing position while pressing the supporting member (31).
