An image forming apparatus includes at least one developing device which may include a photoconductor and a developing roller, a light source configured to generate light to form an electrostatic latent image, a light scanner including a light window through which the light generated by the light source is transmitted, a shutter configured to open or close the light window, and a pressure member moved in response to the opening or closing operation of the shutter or the contact or separation between the photoconductor and the developing roller. The image forming apparatus can easily control the shutter without additional structures, resulting in implementation of a simplified structure. |

1. An image forming apparatus comprising:
a main body; a developing device which includes a photoconductor and a developing roller that forms a visible image by applying a toner to the photoconductor on which an electrostatic latent image is formed and is detachably coupled to the photoconductor; a light scanner which includes a light source which generates light to form the electrostatic latent image by applying the light to the photoconductor, and a light window which transmits the light generated by the light source; a shutter which is rotatably moved among a standby position, an open position at which the light window is opened after being moved from the standby position to allow installation of the developing device, and a close position at which the light window is closed; and a pressure member which includes a pressure-member main body provided to move forward or backward between a first position and a second position, and a pressure protrusion provided to press the shutter and the developing device, wherein the pressure-member main body is interoperable with an opening or closing operation of the shutter or a contact or separation between the photoconductor and the developing roller, wherein the shutter includes: a shutter main body to open or close the light window; and a link device rotatably coupled to the shutter main body so that the link device rotatably moves among the standby position, the open position, and the close position, and wherein the link device includes a mounting protrusion pressed by the developing device when the developing device is mounted so that the shutter is protruded to move from the standby position to the open position. |
