A stapling apparatus includes a stapler, a driver to move the stapler, and a guide part to define a moving path along which the stapler is to move in response to selection of the moving path among a plurality of moving paths along which the stapler is movable.

Stapling apparatus and image forming apparatus including the same

A stapling apparatus capable of performing stapling on various positions by varying a moving path of a stapler is provided. The stapling apparatus includes a stapler, a driver configured to be coupled to the stapler and move the stapler, and a guide part configured to selectively switch a moving path of the stapler.

A method of controlling performance of auto color registration (ACR) of a color image forming apparatus, and an image forming apparatus using the same are provided. The method of controlling performance of ACR includes forming a composite black image on a transfer belt, sensing the composite black image by using a sensor, measuring the sensed composite black image, and performing ACR correction when a measured width of the composite black image is greater than a previously set value. Accordingly, it is possible to prevent unnecessary performance of ACR control when no color misregistration has occurred. In this way, ACR control is performed in as short a time as possible so that performance of the image forming apparatus may be improved. Also, it is possible to prevent waste of ACR performance time and life span reduction of a driving source for ACR.

An image forming apparatus includes an image forming unit to perform printing using a light source unit and a photosensitive medium, a registration unit to adjust an exposure time to correspond to a change in a power of a light source when the power of the light source changes, and a controller to control the image forming unit to perform printing according to the adjusted exposure time.
