Abstract
The present invention relates to a color printer and particularly to a color printer reducing power consumption and complying with international criteria ensuring sustained earth environment. In a color printer having multiple optical writing heads for individual recording colors, the activated periods of individual color recording heads are set to different periods and one writing period of individual recording heads is divided into multiple periods, video data for recording one dot line are divided into multiple blocks in the main scan direction, and the divided video data are used for emission at different times in the sub-scan direction, whereby a smaller number of optical writing elements are simultaneously driven for emission and the peak power consumption of the entire apparatus is reduced.
