Abstract
An image forming apparatus has upper and lower frames. A fixing unit detachably mounted on one frame is provided with a heated roller and a pressure roller. One end of a lever is positioned to be pushed by the other frame when the frames are in a closed condition, and the other end of the lever pushes the pressure roller at both ends of its shaft transversally towards the heated roller so as to pinch therebetween and heat a sheet having a toner image thereon. When the frames are disengaged and moved to their opened condition the pressure on the lever is released, whereupon the pressure roller separates from the heated roller so that the pressure on the sheet is released to facilitate easy removal of the sheet.
