<P>PROBLEM TO BE SOLVED: To provide a toner and a developer for electrostatic charge image development which may prevent occurrence of a soft agglomerate causing an abnormal image in a developing device such as a black spot or a shooting star in toner containing at least a crystalline polyester and a noncrystalline polyester as a binder resin component. <P>SOLUTION: A toner for electrostatic charge image development comprises a crystalline polyester resin, a noncrystalline polyester resin, a release agent and a coloring agent and has a glass transition temperature of 40°C or more and 60°C or less as measured by a differential scanning calorimeter (DSC) for the toner for electrostatic charge image development. The adhesive force between toner particles after storing the toner for electrostatic charge image development at 50°C is 1.4 mN or more and 2.2 mN or less. <P>COPYRIGHT: (C)2012,JPO&INPIT |
