Abstract:
1. A fixing device comprising: a rotatable fixing side member; and a rear side member that rotates in pressure contact with an outer peripheral surface of the fixing side member, the rear side member forming a fixing nip portion for conveying a sheet on which a toner image is formed in a sandwiching manner in conjunction with the fixing side member, wherein velocity difference setting means for setting a velocity difference between a surface velocity of the rear side member and a surface velocity of the fixing side member is provided such that the surface velocity of the fixing side member is lower than the surface velocity of the rear side member, and the rear side member and the fixing side member rotate with a velocity difference set by the velocity difference setting means, wherein the velocity difference setting means sets the velocity difference such that the surface velocity of the fixing side member is lower than the surface velocity of the rear side member by 0.3 to 0.8%.
