Image forming method and image forming apparatus

Abstract

An image forming apparatus, comprises: an electrostatic image-bearing member for holding an electrostatic latent image; a developing means for developing the electrostatic latent image to form a toner image on the electrostatic image-bearing member, the developing means including a non-magnetic color toner developing means for development with a developer comprising a non-magnetic color toner and a magnetic toner developing means for development with a magnetic toner, wherein the non-magnetic toner has a volume-average particle size of 4 to 15 microns, the magnetic toner contains 17 to 60% by number of magnetic toner particles having a particle size of 5 microns or smaller, 1-23% by number of magnetic toner particles having a particle size of 8.0-12.7 microns and 2.0% by volume or less of magnetic toner particles having a size of 16 microns or larger, and the magnetic toner has a volume-average particle size of 4-9 micron and a degree of aggregation of 50-95%; a transfer means for transferring the toner image formed on the electrostatic image-bearing member to a transfer-receiving material; and a cleaning means for blade-cleaning the surface of the electrostatic image-bearing member after the transfer.
