Claims

[Scope of utility model registration request]

A developing device having a plurality of color separation filters that can be inserted into the various exposure paths in a switchable manner, and a developer of a color complementary to at least each of the color separation filters that can be switched and operated along the photoreceptor drum. multiple developing units including;
Wrap the transfer paper and bring it into contact with the photosensitive drum at the transfer position,
It has a transfer drum that rotates in synchronization with this, and in full color copy mode, a color document is exposed through each color separation filter, and each latent image formed on the photoreceptor is colored in a complementary color relationship with the color separation filter through which it has passed. Developed with a certain developer,
The images are superimposed and transferred onto the same transfer paper wrapped around the transfer drum, and in monochrome copy mode, the original is exposed once or multiple times without passing through a color separation filter, and the latent image formed on the photoconductor is transferred to one color. Developed with a developer of multiple colors or a developer of multiple colors that can obtain the color to be copied by color mixing, and one transfer paper is developed with one developer.
A color electrophotographic copying machine that performs overlapping transfer once or multiple times, characterized in that the output of an exposure lamp is switched between a full color mode and a monochrome copy mode.
