Abstract:
The present invention relates to a toner for electrostatic charge image development, including: a toner base particle having at least a binder resin, a releasing agent, and a colorant, wherein the following formula (1) is satisfied wherein a maximum value and a minimum value of a dielectric loss tangent tan δ, which are obtained by measuring at a frequency in the range of 1 kHz to 100 kHz under the condition at a temperature of 20° C. and a relative humidity of 50% RH, are defined as tan δmax and tan δmin, respectively. According to the present invention, a toner for electrostatic charge image development, with which the rising of the toner charge amount is improved while ensuring the low temperature fixability, and a high quality image having less density unevenness can be obtained even during the image forming at a high speed and a high printing rate, is provided. Frequency showing tan δmax
