摘要：An electrophotographic photoreceptor is moved in reciprocatory movementsat least a number of times corresponding to the number of color- selective reflectionand transmission filters in a predetermined zone in which are disposed an exposingstation and a transfer printing station. The electrophotographic photoreceptor iselectrically charged and exposed to an optical image of the original during its

reciprocating movements, with the color-selective reflection and transmission filters usedvarying from one reciprocating movement to another. An electrostatic latent imageformed on the photoreceptor is printed by transfer printing on a transfer printing sheetby bringing the latter into contact with the former each time such image is formed, andthe latent image is converted into a visible image by using a specific developing liquid of acolor corresponding to the color-selective reflection and transmission filter used forforming the latent image. The photoreceptor is repeatedly processed through thecharging, exposing, electrostatic latent image transfer printing and developing steps soas to build up on the same transfer printing sheet visible images of colors for the

respective color- selective reflection and transmission filters whereby a color duplicate ofthe original can be produced.
