Fusing unit to control pressure applied to printing medium, an image forming apparatus having the same and a method for controlling fusing pressure

摘要

A fusing unit of an image forming apparatus is capable of controlling fusing pressure according to detailed types of printing medium without deteriorating printing speed. A first roller rotates about a first rotation shaft CR 1 . A second roller rotates in contact with the first roller about a second rotation shaft CR 2 and is movable along the outer circumference of the first roller. A moving unit relocates the second roller according to a type of printing medium. A pressing unit presses the second roller toward the first roller by applying different pressures according to a position of the second roller with respect to the first roller.
