Abstract
An image forming apparatus is provided. The image forming apparatus includes multiple photoreceptors, a primary transfer unit attachable to and detachable from an apparatus main body, and a unit lock that restricts the primary transfer unit from being detached from the apparatus main body. The primary transfer unit includes a primary transfer belt, multiple primary transfer rollers, and a contact and separation mechanism. The contact and separation mechanism includes multiple arm members, a link member, and a grip. When, using the grip, a user moves the link member to a release position for separating all of the primary transfer rollers from the photoreceptors, the unit lock transitions from a lock state to an unlock state.
