Claim 3:
4. The image forming apparatus according to claim 1, further comprising:
a developing roller that retains a developer;
a first coupling mounted to the developing roller;
a drive gear that transmits a drive force to the developing roller;
a second coupling provided coaxially with the drive gear, rotatable by following rotation of the drive gear, slidable axially relative to the drive gear, and engageable with the first coupling;
a biasing member that biases the second coupling toward the first coupling to connect the second coupling to the first coupling; and
a slide member that is mounted to the body housing in an axially slidable manner, pushes out the second coupling against bias of the biasing member when the rotary member rotates forward, and releases pushing against the second coupling when the rotary member rotates backward,
wherein the rotary member is mounted to the body housing coaxially rotatably with respect to the drive gear, and
the first link member rotates the rotary member forward in conjunction with opening movement of the access opening closure and rotates the rotary member backward in conjunction with closing movement of the access opening closure.
