(57) Abstract: An object of the present invention is to provide an image forming method which exhibits excellent durability without causing an image defect and a deterioration of a developer due to a charging failure even in a developing simultaneous cleaning image forming method. A charging step of charging an image carrier for carrying the electrostatic latent image; an exposure step of forming an electrostatic latent image on the charged image carrier by image exposure; And a transfer step of transferring a toner image formed on the surface of the image bearing member to a transfer material, and a surface of the image bearing member after the transferring step. In an image forming method using a simultaneous development and cleaning method in which the developing device also collects toner remaining in the developing step, the toner may be a carbon black having an average primary particle diameter of 25 to 80 nm of a binder resin. And toner particles containing at least a specific azo-based iron compound and inorganic fine powder. |
