PURPOSE:To remodel the copying machine on the market only a little to obtain a developed picture having the mirror image relation to the original picture and remodel it to the copying machine for production of the dyeing master, by using the in-prism type lens where the prism is arranged in the back of the optical lens. CONSTITUTION:The reflection light from original 5 due to light irradiation from light source 4 is led to recording sheet 1 through optical system 6 and is exposed to light to form an electrostatic latent image. This electrostatic latent image is developed in magnetic brush developing device by the magnetic toner including the dye which is sublimed or evaporated under air pressure at temperature 70-260 deg.C, and this image is transferred and fixed as required. Since lens 62 prism 63 in the back of this lens are arranged in optical system 6 which leads the reflection light of original 5, the electrostatic latent image having the mirror image relation to the original picture is formed on recording sheet 1; and if this optical system 6 is replaced with the in-mirror lens, a copying machine for general noninverted image copy is obtained. |
