<p>PURPOSE:To employ only one rotary drum and only one color of toner and to eliminate the need for a halftone light receptor by dividing a color to be recorded into plural color element images corresponding to coloring materials and rediating light of a specific wavelength corresponding to a toner original image selectively. CONSTITUTION:Light of a wavelength M emitted from a fluorescent lamp 31M is radiated on a toner original image reaching the strip radiation area on a rotary drum 21 via a rotary mirror 32, a slit 34 and a cylindrical lens 35. The light radiated on a drum face where no toner exists is reflected and exposed onto a photosensitive paper sheet 1 through an image forming lens 36. Through the procedure above, with respect to cyan C and yellow Y, the exposure of wavelengths C and Y is applied respectively. After the completion above, a command of a control circuit 46 drives a cam motor 18 to press a pressing roller 16 against a roller 16b and to drive a pressure roller motor 17 thereby smashing unexposed microcapsules 4M, 4C, 4Y into coloring and fixation and forming a desired color permanent image.</p> |
