ABSTRACT:
Improvement has been made in an image forming method comprising charging electrically an image holding member, forming a latent electrostatic image on the image holding member, developing the latent image with a toner, transferring the toner image onto a toner image receiving medium, and recovering untransferred toner. In this method, a magnetic brush formed from magnetic particles electrifies the image holding member by contact with the image holding member surface, recovers temporarily at least a part of the toner remaining on the image holding member after the image transfer, and transfers the recovered toner further again onto the image holding member, wherein the toner has a weight-average particle diameter of not larger than 1/3 of average particle diameter of the magnetic particles and the magnetic particles contain particles of diameter of not larger than 1/3 of the average particle diameter of the magnetic particles at a content ranging from 0 to 50% by volume. Thereby, contamination of the magnetic particles by the toner and interception of the electric conduction path in the magnetic brush are prevented, and deterioration of the toner is prevented without excessive shearing of the recovered toner with magnetic particles.
