Abstract

PURPOSE:To prevent offset trouble in case of using a heat roll fixing system high in heat efficiency and fixing speed by incorporating a composition consisting of a resin having methylol groups and a resin having functional groups each reactive with the methylol group, or incorporating a resin modified by reacting these resins in advance. CONSTITUTION:The resin to be added is the composition consisting of the resin having the methylol groups and the resin having the functional groups each reactive with the methylol group, or the resin modified by reacting these resins in advance. The functional group capable of reacting with the methylol group is carboxylic or hydroxyl group, etc., and the resin having such groups is a styrenic resin or styrene-acrylic-butadiene copolymer, etc., are enumerated, and the resin having the methylol groups is typified by the phenol-formaldehyde resin, thus permitting offset trouble to be overcome, heat roll fixing to be executed, and high-speed fixing to be facilitated.
