Abstract

A simple structure is provided to move an optical print head toward a photosensitive drum. An image forming apparatus includes an optical print head having a first link portion and a second link portion, a sliding portion configured to move by sliding as to an image forming apparatus main body, and an abutting portion where one end of the optical print head abuts. When the sliding portion moves by sliding, the first link portion and the second link portion pivot as to the sliding portion, with the one end of the optical print head abutting the abutting portion, and the optical print head moves toward the photosensitive drum.
