Abstract
A fusing roller is replaceable in an image-forming apparatus in a fusing roller cartridge. The cartridge includes the fusing roller mounted for rotation in a housing, oil-applying structure, heating lamp, temperature sensors and an access opening. A pressure roller in the receiving apparatus frictionally engages the fusing roller to drive it during operation. No separate drive connections are necessary for the fusing roller. Electrical connection with a heating lamp and temperature sensors is provided with a cartridge electrical connector extending from a leading end of the cartridge. The cartridge electrical connector mates with a receiving electrical connector in the image-forming apparatus when the cartridge is inserted by movement parallel to the axis of rotation of the fusing roller. Receiving support structure for the cartridge is tilted to cause the bottom and one side surface of the cartridge to rest gravitationally on the support structure when inserted.
