TONER, DEVELOPER, TONER CHARGED CONTAINER, PROCESS CARTRIDGE, APPARATUS AND METHOD FOR IMAGE FORMING

PROBLEM TO BE SOLVED: To provide a method and an apparatus for image forming using a fixing device of an electromagnetic induction heating system, and to provide a toner, a developer, a container charged with toner, and a process cartridge to be used for the above apparatus and method. SOLUTION: The method for image forming includes an electrostatic latent image forming step, a developing step, a transferring step and a fixing step, wherein a fixing device comprising a magnetic metal and employing an electromagnetic induction heating system is used in the fixing step. The toner comprises a toner material containing at least an active hydrogen group-containing compound and a polymer reactive with the active hydrogen group-containing compound. The toner comprises toner matrix particles having 3 to 7 μm volume average particle size (Dv), 1.01 to 1.25 ratio (Dv/Dn) of the volume average particle size (Dv) to the number average particle size (Dn), having 20 number% proportion of particles having 0.6 to 2.0 μm particle size, and having the average circularity of 0.93 to 0.99. An external additive is added by 0.3 to 5.0 parts by mass to 100 parts by mass of the toner matrix particles. COPYRIGHT: (C)2007,JPO&INPIT
