PURPOSE:To simplify process, by carrying out heating and color development of filter particles, fixing of a toner, and removal of the filter particles in one time. CONSTITUTION:The conductive substrate 10 of a photoreceptor is grounded, uniformly negatively charged in the dark, and a mixture system of 3 kinds of red, blue, and green filter particles are attached to the surface of the photoreceptor 1. It is exposed through the filter particle layer to the optical image of an original O having black, red, blue, and green images on a white ground. Then, the filter particles weakened in adhesion to the photoreceptor 1 are selectively removed to obtain a filter particle image on the photoreceptor 1. A white toner is mixed into a 150-250 mesh iron oxide powder in 3wt% per iron oxide and stirred to form a developer, and the photoreceptor 1 is developed from above the filter particle image, resulting in attaching the white toner T to the filter particle image, and then, the toner T and the filter particles are transferred to a transfer sheet S. |
