IMAGE FORMING METHOD AND MAGNETIC TONER AND DEVELOPER USED THEREIN

摘要

PROBLEM TO BE SOLVED: To solve the problem that satisfactory image density can not be obtained and foggy spots are increased since the electrified amount of MICR toner is low and the magnetic force of the MICR toner restrains developability when MICR toner for a magnetic one- or two-component developer is used in a nonmagnetic two-component developer system in which high speed development is possible. SOLUTION: This image forming method comprises depositing the developer comprising at least a magnetic carrier and toner on a developer carrier having a means for generating a magnetic field on the inside and supplying the developer-deposited developer carrier to a latent image holding body to develop a latent image on the latent image holding body. The toner to be used comprises at least a binder resin, a magnetic material and wax and has 25 emu/g or lower saturated magnetization, 7-20 emu/g residual magnetization and -18 to -35μC/g triboelectrified amount. The magnetic carrier to be used is coated with a resin.
