PURPOSE: To provide a positive charge type toner composition containing a cirtain kind of specified charge accelerating additive and having an excellent rapid mixing characteristic and an allowable triboelectric charge characteristic. CONSTITUTION: A positive charge type toner composition containing, resin particles, pigment particles and bis-(distearyl dimethyl ammonium) sulfate are provided. The toner composition has a desired mixing characteristics of 5-60sec, preferably <=15sec, when measured by a charge spectrogram and the allowable triboelectric charge characteristic of about 10 to about 40 microcoulomb/g. |
