Abstract
An image forming apparatus includes image carriers, holding rollers configured to hold developer attached on the respective image carriers, a belt having a surface which contacts the image carriers and moves in a moving direction, transfer members which transfer the developer on the respective image carriers to the belt, a collection device which collects the developer on the belt, and a control device which executes a cleaning control of causing the developer held on the holding rollers to be moved to the image carriers and the collection device to collect the developer via the image carriers and the belt. The control device starts the cleaning control, suspends the cleaning control before the developer moved to an image carrier from the holding roller positioned at a most downstream side in the moving direction reaches the collection device, and resumes the suspended cleaning control at a next printing preparation control.
