Abstract

PURPOSE: To let positive polarity to be exhibited sufficiently even with a slight amount and obviate receiving any restriction in the kinds of the resins used by containing the specific compound of high charge control effect in the dry type electrophotographic toner composed of phthalocyanine base pigments and resins.
CONSTITUTION: The compound of the formula (R1, R3 are H, CH3, C2H5; R2, R4 are CH3, C2H5; R5, R6 H, are CH3; R7 is H, Cl; Aθ is anion) is contained at less than 10wt% or resin, preferably less than 5wt%, in the dry type electrophotographic positive charge cyan toner composed of phthalocyanine base pigments and preferably styrene base resin used for 3 primary colors of electrophotographic color copiers.
