PURPOSE: To obtain a toner which has excellent fixability and offset resistance and is suitable for fixing with a heating roller by incorporating nonlinear polyester obtd. from a monomer component contg. tri- or higher valent monomers and vegetable wax and/or montan ester wax as well as an antioxidant into the toner for developing electrostatic latent images. n CONSTITUTION: The nonlinear polyester obtd. from the monomer component contg. the tri- or higher valent monomers and the vegetable wax and/or montan ester wax as well as the antioxidant consisting of a phosphorus compd. are incorporated into the toner for developing the electrostatic latent images. The electrostatic latent images formed by an electrophotographic method, electrostatic recording method, electrostatic printing method, etc., are developed by this toner to improve the fixability and offset resistance and are developed by the heating roller. Generation of fogging, and unequal solid black by use in high- temp. and high humidity environment is eliminated and the sharp image characteristic having the excellent durability is obtd. n COPYRIGHT: (C)1989,JPO&Japio |
