Abstract:
1. A toner for developing an electrostatic charge image, comprising: an amorphous polyester resin; a crystalline polyester resin; and a releasing agent, an amount of the releasing agent in the toner being from about 5 to about 15% by weight; an amount of the releasing agent present at a surface of the toner being from about 10 to about 35% by weight; and the toner showing at least one endothermic peak in each of a temperature range from about 45 to about 60° C., a temperature range from about 65 to 80° C. being derived from the crystalline polyester resin, and a temperature range from about 85 to about 100° C. in a temperature-rise process of differential scanning calorimetry of the toner, the toner having a shape factor SFI of from 138 to 155.
