Title: Electrostatic charge image developing toner
Inventor: KABASHIMA HIROTAKA
IPC: G03G9/08
Filed: 1989-02-08
Abstract: PURPOSE:To obtain the electrostatic charge image developing toner having excellent low-temp. fixability, blocking resistance and durability, etc., by specifying the specific surface areas of the toner and base material particles. CONSTITUTION:The specific surface area of the toner is designated as A m<2>/g and the specific surface area of the base material particle as B m<2>/g. These specific surface areas are so determined that the formula I is held. Namely, since the softening point of the binder for the base material particle is as low as <=120 deg.C, the sufficient low-temp. fixability is exhibited by the resulted toner and further, fine resin particles are fixed and applied on the surface of the base material particles by mechanical impact force in the state of satisfying the relation expressed by the formula I and, therefore, the development of the soft characteristics of the base material particle is suppressed. The blocking resistance, filming resistance and flowability are improved in this way.
