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 cross-linked polyester. CONSTITUTION:The cross-linked polyester to be used is as follows; a polyester cross-linked by a polyvalent metal compound, a polyester having carboxyl groups cross-linked by triglycidyl isocyanurate, and a self-cross-linking polyester, thus permitting offset trouble to be overcome, heat roll fixing to be executed, high-speed fixing to be facilitated, and white image dropout to be prevented.
