ABSTRACT:
An image forming apparatus includes a toner image forming device, a toner image conveyer unit, a control device, and a moving device. The toner image conveyer unit includes a toner image conveyer, a supporting member that detachably supports the toner image conveyer, and a detecting member that detects a toner image on the toner image conveyer. The toner image conveyer unit is movable between a first position where the toner image is formed on the toner image conveyer and a second position where the toner image conveyer is attached to or detached from the supporting member. The moving device moves the detecting member located at a position to detect the toner image, away from the toner image conveyer supported by the supporting member, in conjunction with an operation to move the toner image conveyer unit from the first position to the second position.
