PURPOSE: To allow efficient and good fixing with a heating roller without generating the offset that a toner is fused to the surface of a fixing roller by further adding a nuclear agent into the toner contg. a binder, coloring agent and polypropylene. n CONSTITUTION: This electrostatic latent image developing toner is prepd. by incorporating the nuclear agent into the toner consisting of the binder, coloring agent and polypropylene. The nuclear agent to be used includes alum, silica, titanium, calcium oxide, substd. DBS, such as i-propyl DBS and p-chlor DBS, bis(p-ethyl benzylidene) sorbitol, org. carboxylate, org. phosphate, etc. The so-called offset that the roller surface and a part of the toner image stick to the surface of the fixing roller does not arise and the generation of stains on a sheet to be fixed is obviated. n COPYRIGHT: (C)1992,JPO&Japio |
