摘要:
A toner for electrophotography containing a resin binder and a colorant, wherein the resin binder contains a polyester in an amount higher than 50% by weight of the resin binder, wherein the polyester is obtained by polycondensing an alcohol component containing 60% by mol or more of an aliphatic diol having 3 to 10 carbon atoms and a carboxylic acid component comprising 80% by mol or more of an aromatic dicarboxylic acid compound, the polyester having an index of crystallinity of from 0.6 to 1.5, and a glass transition temperature of 0° C. or more and less than 40° C. The toner for electrophotography of the present invention can be used for, for example, developing electrostatic latent images formed in electrophotography, electrostatic recording method, electrostatic printing method, or the like.
