FIG. 1 is a sectional view showing a developing device using the developer according to the present invention, FIG. 2 is a diagram showing the relationship between image density and voltage when using the developer according to the present invention, and FIG. 3 is a diagram showing the relationship between image density and voltage when using the developer according to the present invention. A diagram showing the relationship between image density and voltage using a two-color mixed developer in the absence of a magnetic carrier.
FIG. 4 is a cross-sectional view showing a developing device when non-magnetic toner is used for both toner colors. 1 is a sleeve, 2 is a fixed magnet, 3 is a photoreceptor, 4
is a developer (including 6, 7, and 8), 5 is a developer container, 6 is a magnetic carrier, 7 is a magnetic toner, 7' is a non-magnetic toner, 8 is a non-magnetic toner, and 9 is a developer regulating member. The toners 7 and 8 or the toners 7' and 8 have different polarities.

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
