ABSTRACT:
A developer composition of the present invention contains a toner having at least a binder resin, a coloring agent and a toner scum preventive. The binder resin contains as a main component a polyester resin or a resin produced by concurrently carrying out addition polymerization and condensation polymerization in one reaction vessel. By using the toner of the present invention, since the formation of toner scum on the carrier surface can be prevented for a long period of time in the service life of the developer while retaining the low-temperature fixing ability of the toner, the carrier resistance and the triboelectric charge can be stably maintained, thereby providing a developer composition with a long service life. Accordingly, besides having a long service life mentioned above, the developer composition is highly suitably used for a high-speed semiconductive magnetic development.
