| 英文摘要 | PURPOSE:To realize a high definition picture and also to realize a stable high definition heat tone picture by solving problems in the pulse width modulation system and in the light intensity modulation so ad to employ a laser printer resulting from the combination of the laser scanning technology and the electrophotographic technology. CONSTITUTION:The image forming device is provided with a 1st means 11 setting a pulse width not causing 100% of the exposure time corresponding to a minimum picture element to be recorded and varying the exposed light quantity according to each inputted picture element information, a 2nd means 10 converting the inputted picture element information into picture element information of predetermined MXN sets of patterns based on the MXN sets of picture element information inputted as above, and a 3rd means (selection calculation means) selecting the 1st or 2nd means according to the picture information inputted as above. |
