Abstract
An image-forming apparatus includes a photosensitive drum, a developing roller, a collecting roller, a belt, a cleaner, and a controller. In response to receiving a signal, the controller performs a process staring with a first process and ending with a second process. The controller rotates the developing roller at a contact position at a first speed in the first process. The controller causes the collecting roller to move residual toner to the belt to allow the cleaner to clean the belt while the developing roller is separated from the photosensitive drum in the second process. The process further includes: (a) causing the developing roller to halt rotating while maintaining the developing roller at the contact position; and (b) causing the developing roller halted in the (a) causing to start rotating at a second speed lower than the first speed while maintaining the developing roller at the contact position.
