Abstract: 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.

Abstract: 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.

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.

Abstract: 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.

Abstract: An image forming apparatus and method are provided. The apparatus includes a main body, a developing unit for forming an visible image, a transfer unit for transferring the visible image formed by the developing unit onto a recording medium, the transfer unit being disposed in the main body, a tray loaded with the developing unit and installed to be inserted or withdrawn into or from the main body, a power supply unit for supplying a power supply to the developing unit, the power supply unit being disposed in the main body, and a conductive member that is connected to the power supply unit, intersects an insertion or withdrawal direction of the tray, and directly contacts an electrical contact portion of the developing unit.
