Fixing device and image forming apparatus

Abstract

A fixing device includes a fixing belt member including a base material and a surface layer that is disposed on the base material and is a cured product of a composition containing a siloxane compound represented by Formula 1, a heating member that is disposed on an inner surface side of the fixing belt member, and a pressurizing roll member that is disposed to be in contact with an outer surface of the fixing belt member.
