<p>PROBLEM TO BE SOLVED: To provided an image forming device which ensures reliable image reproducibility even when a microcapsule paper is used as a photosensitive recording medium. SOLUTION: Plural light emitting diodes(LED) driven to emit lights of different colors are provided on an exposure head which is freely movable in a width direction and a paper fed direction, relatively with a microcapsule paper. Data stored in an original image bit map data memory part 100 is processed for chromatic correction using a color corrector 101, then is processed for gradation correction using a gradation corrector 102, and is processed for array conversion using an array converter 103. Next, data per single dot for a single exposure line of each of LEDs is transferred to a PWM buffer 106 through a line sequential sender 104 and a 2-line buffer 105. Further, a PWM clock is counted with the help of a counter 107 until the count is equal to a data value in the PWM buffer 106 and each of LEDs is driven in the modulation mode.</p> |
