<p>PROBLEM TO BE SOLVED: To provide a process cartridge in which fog and electrification failure are hardly caused without influenced by the environment, and to provide a method for forming images by using that cartridge. SOLUTION: The process cartridge 13 consisting of a developing cartridge containing a toner, magnetic carrier, toner carrying body and doctor blade, or consisting of a drum cartridge containing an electrostatic charge image holding body, noncontact electrifying means to electrify the image holding body, and cleaning means equipped with a cleaning blade to recover the toner not transferred is attached to the main body of the device for image formation. An image is formed by using a developer which contains a toner having toner particles having 7.5 to 10.5μm weight average particle size and 1.1 to 1.3 true specific gravity and containing a binder resin and magnetic fine powder and which contains a magnetic carrier coated with a resin and having 40 to 80μm weight average particle size and 6.0 to 8.0 true specific gravity.</p> |
