ABSTRACT:
An image forming method by the electrophotographic process is disclosed. The image forming method comprises the steps of forming a plurality of toner images different in color on an image carrying member by repeating the developing of the electrostatic latent image on the image carrying member with developers containing both toner and carrier, and transferring said plurality of the toner images at a time onto a receiving material, in which the toner to be provided for at least the initial toner image formation is mixed with 0.2 to 2% by weight of metal oxide particles having a BET specific surface area determined by nitrogen adsorption of from 30 m.sup.2 /g to 60 m.sup.2 /g. The method provides clear multicolor images free from any deterioration in the resolution due to transfer doubling trouble as well as in the image quality due to transfer-off spots.
