IMAGE FORMING SYSTEM, METHOD AND DEVICE FOR CORRECTING DEVIATION OF POWER SOURCE VOLTAGE IN IMAGE FORMING SYSTEM, AND WRITE-IN MEDIUM READABLE BY COMPUTER

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for correcting the deviation of power source voltage in an image forming system.

SOLUTION: The image forming system is constituted of an image density sensing part sensing image density, a 1st deviation correction part calculating the deviation by comparing the 1st power source voltage of the image density sensing part with a 1st reference value and correcting it by applying correction amount according to the calculated deviation to the image density sensed by the image density sensing part, an environment detection value measuring part measuring the resistance value of a roll for detecting environment, and a 2nd deviation correction part calculating the deviation by comparing the 2nd power source voltage of the environment detection value measuring part with a 2nd reference value and correcting it by applying the correction amount according to the calculated deviation to the resistance value of the roll measured by the environment detection value measuring part.
