Abstract
There is provided a tandem color image forming apparatus and the like, which is capable of suppressing the generation of black spots during a continuous image forming process, even though a non-magnetic single-component developer is used and a cleaner-less type is adopted. The color image forming apparatus is a tandem type that includes a plurality of image carriers and a cleaner-less type that does not include a blade cleaner, wherein the resistance per square centimeter of a base body of an image carrier using for at least a black developer among the plurality of image carriers, or the resistance per square centimeter of the base body through an intermediate layer is set in a range of 1×105 to 1×108Ω or more.
