Abstract: Disclosed herein is an image forming apparatus. The image forming apparatus includes a light scanning unit including a light source which generates light to form an electrostatic latent image by applying the light onto the photoreceptor, and a window through which the light generated by the light source is transmitted, a shutter unit which opens and closes the window, a plurality of pressing units which are provided to allow pressing the developing unit and the shutter unit for an operation of attaching or detaching the developing roller to or from the photoreceptor and an operation of opening and closing the shutter unit and are disposed and spaced in a longitudinal direction, and an operating unit movably provided between an operating position at which a pressing force of the plurality of pressing units is generated, and a standby position at which the pressing force is released. By this configuration, an operation of opening and closing the shutter unit is allowed to link with an operation of attaching or detaching the developing roller to or from the photoreceptor.
