PURPOSE:To provide an image forming device capable of properly controlling a toner concentration and a fixing temperature according to various kinds of image forming conditions by making the hard ware constitution of a process unit common. CONSTITUTION:The image forming device has a correction conditions generating means such as a ROM 32 generating the correcting conditions of a process speed, etc., participating in the correction of a concentration in the replenishment of toner 21 by a toner replenishing solenoid 9, a toner concentration sensor 22 measuring the concentration in the replenishment of the toner 21, an EEPROM 7 storing a series of toner concentration correction data corresponding to the level of the correcting conditions stepwise and a CPU 31 calculating a proper toner replenishment deciding level based on prescribed toner concentration correction data corresponding to the level of the correcting data conditions out of a series of the toner concentration correction data and comparing the toner replenishment deciding level with a toner sensor output level T0, to control the actuation of the toner replenishment solenoid 9. |
