Abstract

PURPOSE:To obtain a positively chargeable toner fit for developing electrostatic charges and having high endurance to continuous copy by using indanthrone pigment as a charging controller. CONSTITUTION:Indanthrone pigment represented by formula I (where each of R1 and R1' is H, Cl or Br; each of R2 and R2' is OH, NH2 or the group of formula II; and each of R3 and R3' is H or CH3), e.g., the pigment of formula III is used. A 100pts. binder resin such as styrenebutadiene copolymer, 1-10pts. said indanthrone pigment, carbon black, etc. are mixed, melted and kneaded, and then the kneaded material is cooled and pulverized to obtain a toner.
