Fixing device and image forming apparatus

摘要

A fixing device (60) and an image forming apparatus include: a rotatable fixing side member (62); a rear side member (64) that rotates in pressure contact with an outer peripheral surface of the fixing side member, the rear side member forming a fixing nip portion (N) for conveying a sheet (S) on which a toner image is formed in a sandwiching manner in conjunction with the fixing side member; and velocity difference setting means (600) for setting a velocity difference between a surface velocity of the rear side member and a surface velocity of the fixing side member, wherein the rear side member and the fixing side member rotate with a velocity difference set by the velocity difference setting means.
