Patent ID: 8592124

Claim:
A toner having: a fixation temperature of from 100° C. to 135° C.; a peak temperature before fixation T 1 a of about 40° C. or more; and a peak temperature after fixation T 1 b that is lower than T 1 a by from about 10° C. to about 35° C.: T 1 a being a peak temperature of an endothermic peak occurring at the lowest temperature in a range of from 0° C. to 100° C. and obtained at a first warming-up step of a differential scanning calorimetry measurement that uses a toner before fixation as a sample; and T 1 b being a peak temperature of an endothermic peak occurring at the lowest temperature within a range of from 0° C. to 100° C. and obtained at a first warming-up step of a differential scanning calorimetry measurement that uses a toner after fixation as a sample; and the toner comprising a binder resin comprising a crystalline polyester resin and a non-crystalline polyester resin or comprising two kinds of polymers polymerized from a monomer mixture comprising styrene and n-butyl acrylate.
