ABSTRACT:
A color image forming apparatus has a plurality of developing devices. Each developing device has developer that includes a predetermined ratio, in volume of developer particles having a diameter of a predetermined value or less, with respect to an entire volume of toner. Each developing device is capable of developing a latent image using the developer. A color image is formed by successively performing development operations so as to superimpose different kinds of developer.
