ABSTRACT:
In a method for printing in an electrophotographic manner a number of duplicated copies by repeatedly effecting developing and transferring steps for the same and single electrostatic charge latent image once formed on a charge retentive member such as a photoconductive drum, in order to compensate a variation in print density of a number of copies an amount of toner particles to be supplied to the latent image during the developing step is adjusted in such a manner that the copies have substantially the same print density. The adjustment of an amount of toner particles can be effected by changing a supply speed of the toner particles, a thickness of a magnetic brush, a distance from the magnetic brush to the latent image, etc.
