摘要： An image forming apparatus includes an image forming unit and a supporting mechanism that supports this image forming unit. A feed tray for placing sheets thereon is provided in a rear part of the image forming unit. The supporting mechanism includes a base member and a turntable. The turntable can move along a guide section to a first position on a rear side and a second position on a front side with respect to the base member. The supporting mechanism includes a rotation stopping mechanism that prevents the turntable from rotating when the turntable is in the first position and a rotating mechanism that rotates the turntable in a horizontal plane in a state in which the turntable has moved to the second position.
