Abstract
An electrophotographic image forming apparatus is provided using a continuous form recording medium, in which the recording medium is nipped between a pair of fixing rollers, at-least-one of which is driven to rotate. The recording medium is fed in response to the rotation of the pair of fixing rollers. The peripheral speed of the at-least-one roller of the pair of fixing rollers is set to be faster than that of the photoconductive drum by a predetermined ratio so that slack of the recording medium between the photoconductive drum and the fixing rollers may be eliminated. Thus, the recording medium is fed properly without the occurrence of skewing between the photoconductive drum and the fixing rollers.
