摘要： An image forming apparatus includes a controller that starts a forced drive stop sequence for stopping image formation at least by stopping rotation of a developer carrier in a first direction when a number of printed sheets reach a threshold. The forced drive stop sequence rotates the developer carrier in a second direction for a prescribed time period when the image formation is stopped. The forced drive stop sequence stops the rotation of the developer carrier in the second direction and resumes the image formation after the prescribed time has elapsed.
