Toner for developing an electrostatic latent image comprising linear polyester polymer

摘要

To overcome the problem of offset images in electrophotography when using a heated roller in fixing a toner image, a toner composition containing a non-linear polyester resin is used. The polyester resin is made from 1-60 mol % polyhydric alcohol having at least three hydroxy groups and 2-65 mol % of a polycarboxylic acid having at least three carboxy groups.
