Abstract

An image forming apparatus is provided. The image forming apparatus includes a sensing unit configured to check a transfer belt, which serves to transfer a visible image to a printing medium, the image forming apparatus capable of reducing contamination of sensors since a lighting window of a sensor provided in the sensing unit is open and closed by a shutter and a shutter driving device.

Description

technical field [0001] Embodiments of the present disclosure relate to an image forming apparatus having a sensing unit configured to inspect toner on a transfer belt. Background technique [0002] Generally, an image forming device is a device capable of forming an image on a printing medium. Types of image forming apparatuses include printers, copiers, facsimiles, and multifunction devices that have the functions of two or more of the printers, copiers, and facsimiles. [0003] The image forming apparatus includes a main body provided with an opening at one side thereof, and a side cover rotatably mounted on the main body to open and close the opening. The inside of the main body is provided with: a plurality of developing units, which develop the electrostatic latent image into a visible image with toners corresponding to various colors; A latent electrostatic image is formed on the photoconductor; a transfer device, which transfers the visible image developed on the ph...
