Abstract
An image forming apparatus can inhibit an occurrence of downtime or shorten the downtime even in a case in which a mode for performing image formation and a position of, for example, a primary transfer member does not match. The image forming apparatus includes photosensitive drums each configured to bear a toner image, primary transfer members, an intermediate transfer belt, an abutment/separation mechanism configured to move the primary transfer members, and a controller. The controller brings the primary transfer members into contact with the photosensitive drums in a full-color mode, separates the primary transfer members from the photosensitive drums in a monochrome mode, and sets the position of the primary transfer members to a predetermined position between that in the full-color mode and the monochrome mode in a standby mode.
