An image forming apparatus includes a photosensitive body on which an electrostatic latent image is formed, an exposure device to irradiate light to the photosensitive body to form the electrostatic latent image, a developing device to adhere a developer to the photosensitive body to form a visible image, a transfer device to transfer the visible image formed on the photosensitive body onto a printing medium, and a fusing unit to fuse the visible image to the printing medium. The fusing unit includes a heating roller to apply heat to the printing medium, a press roller to contact the heating roller to press the printing medium, a press lever to press any one of the heating roller and the press roller to the other, an adjusting lever rotatably coupled to the press lever, and a pressing force adjusting device to operate the adjusting lever to move the press lever. Accordingly, a fusing pressure between the heating roller and the press roller can be decreased with a small force by operating the adjusting lever hingedly coupled to the press lever.
An image forming apparatus, comprising:
A fusing unit, comprising:
A method of automatically controlling a fusing operation of an image forming apparatus for printing media of different thicknesses, the method comprising:
A system to automatically control a fusing pressure on printing media having different thicknesses, comprising:
