Image forming apparatus

An image forming apparatus comprising:

• a housing that has a top opening formed on a top face of the housing and a side opening formed on a side face of the housing;
• an imaging device that is housed in the housing and that includes a photosensitive body, an exposure device which exposes the photosensitive body to form an electrostatic latent image on the photosensitive body, and a developing device which develops the electrostatic latent image with a developer on the photosensitive body;
• a top cover that is movable between an open state opening the top opening and a close state closing the top opening, the exposure device being attached to an inner face of the top cover;
• a moving device that is movable between a first position and second position through the side opening so as to draw a part of the imaging device mounted on the moving device, the first position being set inside the housing, the second position being set outside the housing;
• and
• a state holding device that keeps the top cover in the open state when the moving device is moved from the first position to the second position after the top cover is opened,
• wherein a tip of the exposure device is closer to the photosensitive body than an upper surface of the developing device.
