ABSTRACT:
A toner for development of electrostatic latent images, comprising a resin binder comprising a resin having a softening point of from 120° to 170° C., a glass transition point of from 58° to 75° C., and a percentage of chloroform-insoluble component of from 5 to 50% by weight; and a resin having a softening point of 90° C. or more and less than 120° C., a glass transition point of from 58° to 75° C., and a percentage of chloroform-insoluble component of less than 5% by weight; and at least one low-melting point wax having a melting point of from 60° to 90° C. The toner for development of electrostatic latent images has low lowest fixing temperature and is excellent in the offset resistance, the blocking resistance and the durability.
