ABSTRACT:
A fusing roller is replaceable in an image-forming apparatus in a fusing roller catridge. The cartridge includes the fusing roller mounted for rotation in a housing, oil-applying device, 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. The oil-applying device in the cartridge is accessible from outside the cartridge for adjustment between a condition applying oil and a condition not applying oil. Oil is supplied from a source in the receiving apparatus. A connector on the cartridge mates with a check valve on the receiving apparatus in response to insertion of the cartridge.
