Abstract:
Provided is a toner for electrostatic charge image developing, comprising a core layer which contains a first binder resin and a coloring agent, and a shell layer which contains a second binder resin and covers the core layer, characterized in that the following equation (1) and the following equation (2) are satisfied, 2.0×105≦G′(60)≦4.0×106 Equation (1) 10≦G′(60)/G′(80)≦40 Equation (2) wherein, in the equation (1) and the equation (2), G′(60) represents a storage elastic modulus (Pa) of the toner for electrostatic charge image developing measured under the conditions of a temperature of 60° C., a vibration frequency of 6.28 rad/sec, and a strain amount of 0.01 to 0.5%, and G′(80) represents a storage elastic modulus (Pa) of the toner for electrostatic charge image developing measured under the conditions of a temperature of 80° C., a vibration frequency of 6.28 rad/sec, and a strain amount of 0.01 to 0.5%. Also provided is a developer for electrostatic charge image developing comprising the toner and a carrier, and an image forming apparatus using the toner.
