Claim 16:
17. The image forming apparatus of claim 14, wherein
the first body includes a first surface which is perpendicular to the axial direction and faces away from the end part of the first shaft,
the first plurality of protrusions have a first side which faces in a first circumferential direction of the first shaft and which is inclined with respect to the first surface, and a second side which faces in a second circumferential direction of the first shaft and which is perpendicular to the first surface,
the second body includes a second surface which is perpendicular to the axial direction and faces away from the end part of the second shaft,
the second plurality of protrusions have a first side which faces in the second circumferential direction of the first shaft and which is inclined with respect to the second surface, and a second side which faces in the first circumferential direction of the first shaft and which is perpendicular to the second surface,
when the second side of the first plurality of protrusions is engaged with the second side of the second plurality of protrusions, the developing roller is rotatable in a first direction, and
when a rotational force is applied to the first coupler in a second direction, the first side of the first plurality of protrusions is to engage with and slide along the first side of the second plurality of protrusions, to disengage the first coupling structure from the second coupling structure.
