An image forming apparatus includes a movement mechanism. The movement mechanism moves a pressing mechanism from a first position to a second position along with a start of an image forming operation and moves the pressing mechanism from the second position to the first position along with an end of the image forming operation, when image formation is carried out. The movement mechanism moves the pressing mechanism from the first position to the second position along with detection by a detection unit that a main body cover is opened, when the image formation is not carried out.
