An image forming apparatus includes a developing device including a photosensitive unit having a photoreceptor and a developing unit having a developing. A light scanning unit including a light source may be included to generate light to form an electrostatic latent image on the photoreceptor through a window through which the light is transmitted, and shutter unit may be included to open and close the window. At least one pressing unit is provided to press the developing unit to cause the developing roller separated from the photoreceptor to contact the photoreceptor. The pressing unit may further cause the shutter unit to open and close the window. An operating unit is connected to the at least one pressing unit. The operating unit is movable between an operating position to generate a pressing force by the at least one pressing unit to press the developing unit to contact the photoreceptor and a standby position to release the pressing force.

Image forming apparatus

An image forming apparatus includes a developing device including a photosensitive unit having a photoreceptor and a developing unit having a developing roller; a light scanning unit including a light source to generate light to form an electrostatic latent image on the photoreceptor and a window through which the light is transmitted; a shutter unit to open and close the window; a plurality of pressing units to press the developing unit to cause the developing roller separated from the photoreceptor to contact the photoreceptor and cause the shutter unit to open and close the window; and an operating unit connected to the plurality of pressing units. The operating unit is movable between an operating position to generate a pressing force by the plurality of pressing units to press the developing unit and the shutter unit and a standby position to release the pressing force.

An image forming apparatus includes a body, at least one developing cartridge, which is disposed inside the body to form an image and is provided at one side thereof with an interface terminal to receive a power, a tray movably coupled to the body while accommodating the at least one developing cartridge, a cover coupled to one side to open/close the body such that the tray moves to outside the body, a link member configured to guide the movement of the tray and to move according to the open/close movement of the cover while being connected to the cover, and a connection terminal configured to make contact with the interface terminal by being pressed by the link member when the cover closes the body and to be separated from being released for pressing force when the cover opens the body.
