Abstract

PURPOSE:To obtain an electrostatic charge developing toner with a high quality hardly causing a copy stain, etc., even in the lapse of time by incorporating one or more specified chemical compounds. CONSTITUTION:This electrostatic charge developing toner incorporates one or more chemical compounds represented with formulae I, II. In formula I, Ar<1> and Ar<2> are substituted or unsubstituted alkyl groups or substituted or unsubstituted aralkyl groups, which may be, individually, the same or different, and X-represents an anion and in formula II Ar<3> represents a substituted or unsubstituted alkyl group or a substituted or unsubstituted aralkyl group and X-represents an anion. When the contents of the chemical compound represented with formula I or II are too small, the improved effect of the electrostatic property is not expected and when it is in excess, the quality of the toner is degraded. As the structural component of the toner, the additive of a low molecular weight of an olefinic polyester or particulate silica, etc., may be incorporated. As the manufacture of the toner, respective components are kneaded with a kneader, etc. and after cooled, are pulverized and classified.
