摘要： A pixel information acquiring unit acquires multilevel pixel information in which one pixel is expressed in multilevel scales. A line pixel information storing unit stores the multilevel pixel information for each main scanning line. A light emission control unit optically exposes a photosensitive element by controlling a binary light source on the basis of the multilevel pixel information. The photosensitive element is exposed to the binary light source with a period corresponding to N-fold in a sub scanning direction resolution of the multilevel pixel information, wherein N is a positive integer, so that the N times exposures corresponds to an exposure for one pixel in an original resolution. The switch on/off statuses of the binary light source are controlled in the N times exposures for each pixel, on the basis of lighting rate information for converting the multilevel scales into a lighting rate in the N times exposures.
