装置。 The recording medium on which the latent image has been formed is processed by a developing roller.
In a developing device having a two-type mixed toner that performs development using one type of toner among two types of toner, the developing roller is composed of a magnet roller having a large number of magnetic poles and a non-magnetic material on the outer periphery of the magnet roller. There are two types of toner (positively charged toner and negatively charged toner), one of which is a magnetic toner and the other is a non-magnetic toner.
Two types of developer characterized in that the two types of mixed toner are mixed with a magnetic carrier, and the two types of toner and the magnetic carrier adhere to the sleeve surface to form a developer layer. A developing device that mixes
