Abstract: An image forming device includes a fixed frame, a slide frame, a head supporting frame, a cam structure, and an operation body. The fixed frame is arranged adjacent to a photosensitive body. The slide frame is supported in a slidable manner along a first axis line by the fixed frame. The head supporting frame is supported in a slidable manner along a second axis line, which intersects the first axis line, by the fixed frame, and supports an exposure head. The cam structure converts an operation in which the slide frame slides to an operation in which the head supporting frame slides. The operation body moves the exposure head between a separated position and a proximate position by sliding the slide frame.
