Abstract

PURPOSE:To prevent offset development trouble in the case of using a heat roll fixing system high in heat efficiency and fixing speed by incorporating a self-cross-linking polymer and a cross-linked polymer. CONSTITUTION:It is preferred to use as the cross-linked polymer and the self- linking polymer to be used a copolymer or a modified polymer containing diene- type monomer units each having a conjugated double bond, especially, a copolymer of a vinyl compound and a compound having a conjugated double bond, such as styrene-butadiene copolymer, styrene-chloroprene copolymer, styrene- isoprene copolymer, styrene-piperylene copolymer, or acrylonitrile-butadiene copolymer, thus permitting offset development trouble to be suppressed, heat roll fixing to be executed, and high-speed fixing to be facilitated.
