An image forming apparatus includes: an image carrier (1) rotated by a drive section (100) and carrying a toner image to transfer onto a transfer medium (6); and a drive-side coupling (120) and an image carrier-side coupling (130) capable of being connected to and being separated from each other by relative movement in a direction of a rotary shaft (110) of the drive section (100) and capable of connecting and separating the drive section (100) and the image carrier (1). The drive-side coupling (120) has a plurality of abutting surfaces (122,123) for transmitting a driving force, the image carrier-side coupling (130) has a plurality of abutting surfaces (132,133) to which the driving force is transmitted, and the drive-side coupling (120) and the image carrier-side coupling (130) have a difference in angles of each of the abutting surfaces of the couplings with respect to a direction in which the couplings are connected to and separated from each other. |
