摘要

PROBLEM TO BE SOLVED: To provide a high voltage power supply device which supplies stable and high voltage output at low cost, and provide an image-forming device, a method for controlling high voltage power supply, a method for controlling the formation of an image, a program for controlling high voltage power supply, a program for controlling the formation of an image, and a recording medium therefor.;SOLUTION: In the image-forming device 1, a pulse-generating part 14 generates driving pulses corresponding to a PWM (Pulse Width Modulation) duty from a CPU 11, and a high voltage-generating part 20 generates high voltage output corresponding to the driving pulses to feed back a feedback signal corresponding to the generated high voltage output. Furthermore, the CPU 11 controls the PWM duty to the pulse-generating part 14 on the basis of a target output value and a feedback value to control the pulse widths of the driving pulses that the pulse-generating part 14 outputs. Furthermore, a comparison part 17 compares the feedback value of the feedback signal with a feedback target value set by the CPU 11, for each prescribed control cycle, to make a masking part 18 mask the driving pulses output from the pulse-generating part 14 to the high voltage-generating part 20.;COPYRIGHT: (C)2010,JPO&INPIT
