Abstract

A toner including a binder resin including a crystalline polyester and a non-crystalline resin; a release agent; and a black metal-containing material having a saturation magnetization not greater than 50 emu/g. A toner container containing the toner. A fixing method including passing a support with the toner image thereon through a nip between two cylindrical rollers while applying a pressure not greater than 1×105 Pa to the two cylindrical rollers, wherein one of the cylindrical rollers which contacts the toner image has a thickness not greater than 1.0 mm. An image forming method including developing an electrostatic image with the toner to form a toner image; transferring the toner image onto a receiving material; and fixing the toner image by the fixing method mentioned above. A process cartridge including an image bearing member and a developing device using the toner.
