Abstract

PURPOSE:To dye only specified part black with black dry ink by irradiating a convex surface light transmission part with laser beam light, removing charge from a light receiving part and then using the black dry ink so that black-dyeing is executed to a light shading part by a correspondingly applying electrophotographic technique. CONSTITUTION:Discharge is executed between the surface of a lenticular lens 111 and a corona discharge unit 113 and charge is electrified on the surface of a photoconductive film 112 stuck to a sheet. Then destaticization is executed by using the laser beam light whose diameter is made equal to the width of the convex surface light transmission part 216 which is not dyed black and sequentially scanning 1211, 1212... every stripe. Next, pulvelized black dry ink 131 is scattered on the surface of the sheet and electrostatically sucked to the high voltage electrification part of the photoconductive film 112 to be stuck. Then the sheet and the black dry ink on the sheet are heated to dissolve a resin binding agent included in the ink and the ink is fixed on the light shading part. Thus, the black-dyeing can be precisely executed in a simple method.
