ABSTRACT:
A resin binder for a toner comprising a crystalline polyester having a ratio of a softening point to a maximum peak temperature of heat of fusion (softening point/peak temperature) of from 0.6 to 1.3, wherein the crystalline polyester is prepared by polycondensing a monomer mixture comprising 0.1 to 10% by mol of at least one monovalent aliphatic compound selected from the group consisting of a monovalent aliphatic carboxylic acid compound having 10 to 24 carbon atoms and a monovalent aliphatic alcohol having 10 to 24 carbon atoms; a toner comprising a resin composition comprising the resin binder as defined in above; and a method for fixing a toner, wherein the toner as defined in above is applied to a heat-and-pressure fixing method. The toner comprising the above resin binder is used for developing electrostatic latent images formed in electrophotography, electrostatic recording method, electrostatic printing and the like.
