Abstract
A thermal fixing-type developer material for electrophotography comprising a propylene-.alpha.-olefin copolymer wax (A) having a number average molecular weight (Mn) in the range of from 7,000 to 12,000; a binder (B); and a colorant (C). There is provided a thermal fixing-type developer material for electrophotography which, when used as a main component for an electrostatic toner, would provide a reprographic image which exhibits good release properties upon thermal fixing, a reduced adhesion to the heated roller or the photoreceptor, no offset or contamination, and a good fixing of the fixed image, and prevent the heated roll and the photoreceptor from undergoing contamination.
