Abstract:
A laser output control device to be used in a wet-type electro photographic printing apparatus having a photoconductor drum with a surface on which an image is formed, a charging means for charging the surface of the photoconductor drum, an exposure means for preparing an electrostatic latent image by irradiating a laser beam on the surface of the photoconductor drum, and a developing means for developing the electrostatic latent image on the surface of the photoconductor drum by stacking a plurality of colors thereon, comprising:a laser output data memory part for storing laser output data for each color of every combination of the plurality of colors; a color combination data memory part for storing drawing data as color combination data for each of pixels; a laser control part for controlling the laser beam by selecting laser output data corresponding to a color to be drawn, wherein the laser control part selects the color to be drawn from the color combination data in the color combination data memory part, selects a pixel including the color to be drawn, selects a pixel having the same color combination as that of the selected pixel from the laser output data memory part, together with selecting the same color as the color to be drawn from the pixel, and provides the laser output data corresponding to the selected color as laser output data of the color to be drawn.
