Abstract
An image forming apparatus having an improved structure of simply executing contact or separation between developing rollers and photoconductors is provided. The image forming apparatus includes a cover opening and closing a side of a main body, a photoconductor unit including a photoconductor, a laser scanning unit irradiating the photoconductor to form an electrostatic latent image and including a light source generating light and an optical window transmitting the light generated from the light source, a developing unit supplying a developer to the photoconductor and including a developing roller contacting or separated from the photoconductor, and a shutter unit operable in connection with the cover, opening the optical window when the cover closes the side of the main body, and closing the optical window when the cover opens the side of the main body.
