Abstract: A fixing unit and an image forming apparatus including the fixing unit. The fixing unit includes a heating roller having an internal space in which a heating source is disposed and a pressurizing roller facing the heating roller. The heating roller has a circular hollow pipe shape and includes a fixing nip forming part which forms a fixing nip between the fixing nip forming part and the pressurizing roller. The nip forming part can have a slim part disposed at a center thereof and a pair of deformation preventing parts formed at both ends of the slim part, each deformation preventing part having a thickness thicker than a thickness of the slim part.

Abstract: An image forming apparatus and a color registration method thereof. The color registration method includes checking a change in a status of an image forming apparatus, selecting color registration patterns having a different length according to the status change, and performing color registration by printing the color registration patterns having the different length onto a transfer belt.

Abstract: A unit installable in an apparatus and a method of managing a unit installed in an apparatus are provided. The unit includes a container for a consumable, and a chip mounted to the container. The chip includes a first memory to store data that is accessible and decodable by the apparatus to authenticate the unit. The chip includes a second memory to store recycling prevention information.

Abstract: A heater for a fusing apparatus that is used in an image forming apparatus includes a carbon fiber filament; a holding pipe which receives the carbon fiber filament; and terminals which are disposed opposite ends of the holding pipe and connects the carbon fiber strands with an electric power source. The carbon fiber filament may be formed of any of one to seven carbon fiber strands and each of the carbon fiber strands may have linear density of any of 1-70 tex.

Abstract: An image forming apparatus and an auto color registration method thereof. The image forming apparatus performs an auto color registration (ACR) operation by excluding or minimizing the influence caused by variation in speed of a drive unit driving a transfer member. The image forming apparatus includes a controller, which prints a test pattern of each color according to a rotation period of the drive unit, and controls an operation for outputting an image in which each color registration error is corrected on the basis of the test pattern, such that a reliability of the ACR operation is increased and a quality of an image output from the image forming apparatus is also increased.
