Abstract:
1. A toner, comprising: a binder resin comprising a crystalline polyester resin having a urethane and/or urea bonding; and a colorant, wherein in a diffraction spectrum of the toner as measured by an X-ray diffraction instrument, a ratio {C/(C+A)} of an integral intensity C of a spectrum derived from a crystalline structure to an integral intensity A of a spectrum derived from a non-crystalline structure is 0.16 or greater, wherein the toner satisfies the following relation 1: where T1 represents a maximum endothermic peak in a first temperature rising from 0° C. to 100° C. at a temperature rising rate of 10° C./min and T2 represents a maximum exothermic peak in a first temperature falling from 100° C. to 0° C. at a temperature falling rate of 10° C./min as T1 and T2 are measured by diffraction scanning calorimetry (DSC).
