現像器。 Each developing roller has a plurality of developing devices containing two-component developers containing toners of different colors.
arranged so as to face one another around the two photoreceptors,
In a developing device of a multicolor copying machine in which an electrostatic latent image formed on the photoreceptor is developed by any one of the developing devices, one of the developing devices facing the photoreceptor of the developing roller of each of the developing devices is provided. A toner collection roller to which a bias potential of opposite polarity to the toner in the developer can be applied is provided adjacent to the developing roller on the upstream side, and the bias potential is controlled so as to be applied to the toner collection rollers of the developing devices other than those of the developing color. It features a wet developer.
