Abstract (en)
A toner including a binder resin; and a colorant including an iron oxide compound including Ti in such an amount that the weight of Ti atom is from 10 to 45 % by weight based on the weight of Fe atom therein when measured with a wavelength dispersive fluorescent X-ray analyzer, wherein the content of the black iron oxide compound in the toner is from 15 to 40 % by weight, and the coercive force of the toner is from 2 to 15 kA/m in a magnetic field of 398 Am<2>/Kg when measured with a multi-sample rotation type magnetization measurement system from Toei Industry Co., Ltd. A toner container containing the toner. A two-component developer including the toner and a carrier. An image forming method in which a toner image is formed by performing charging; latent image forming; developing using a developer including the toner; image transferring; image fixing; and cleaning. A process cartridge (30) including at least a developing device (33) using the toner and a housing (35). <IMAGE>
