<P>PROBLEM TO BE SOLVED: To provide a toner for electrostatic charge image development using a polyester resin as a binder resin that has excellent low-temperature fixability, and forms images having excellent image density in a high-temperature environment as well as in a low-temperature environment. <P>SOLUTION: A toner for electrostatic charge image development uses a polyester resin as a binder resin; the polyester resin contains at least colorant, a charge control agent, and a mold release agent. The toner for electrostatic charge image development has the melting point of the toner measured by a constant-load orifice-type flow tester of 110°C or less, and the torque values of the toner measured by a viscoelasticity measuring device of 100 μNm or less at 25°C and 105 μNm or less at 45°C. <P>COPYRIGHT: (C)2013,JPO&INPIT |
