<P>PROBLEM TO BE SOLVED: To improve toner replenishing precision when process linear velocity is switched. <P>SOLUTION: A toner concentration sensor output compensation method stores outside input voltage when variation in output of a toner concentration sensor 56 is adjusted by the outside input voltage, predicts difference in output from a toner concentration sensor 56 before and after switching of the process linear velocity when the process linear velocity is switched in the same toner concentration by two component developer from the stored outside input voltage and output value of the toner concentration sensor 56 when the process linear velocity is switched based on the predicted difference in the output in the toner concentration sensor 56 is compensated. <P>COPYRIGHT: (C)2007,JPO&INPIT |
