<p>PURPOSE:To provide the developer for dry processing with which the sufficient dispersibility of a charge control agent is obtainable and which can output images free from fogging, is stable in electrostatic chargeability, does not flocculate, has an excellent flow property, eliminates the charge control agent peeling from toners, enhance the durability of the toners or the durability of a photosensitive body and facilitates cleaning. CONSTITUTION:A binder and coloring materials are at least mixed and the mixture is pulverized and classified, by which about 10mum coloring particles are formed. The charge control agent is stuck to the surfaces of the coloring particles, by which the charge control agent is included always in one toner particle. Not the effect of the charge control agent in the assemblage state of the toners is expected but each one of the toner particles has sufficient electrostatic charge capacity and electrostatic charge stability. The electrostatic chargeability over the entire part is uniformalized as well.</p> |
