DEVELOPING AGENT FOR HEAT FIXING TYPE ELECTROPHOTOGRAPHY.

摘要

A developing agent for heat fixing type electrophotography, which contains polypropylene/ alpha -olefin copolymer wax A with number-average molecular weight Mn of 7000-12000, a binder B and a coloring agent C. The present invention is capable of providing a developing agent for heat fixing type electrophotography, which is used as a main component of electrostatic toner, displays an excellent mold releasing capability during a heat fixing operation, has an improved deposit-developing effect on a heating roll and a photosensitive body, enables a copied image of an excellent fixability to be obtained free from an offsetting phenomenon and contamination of image, and can prevent a heating roll and a photosensitive body from being contaminated.
