Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To prevent sudden toner replenishment caused by the fluctuation in environmental condition and to always obtain stable image density by deciding the next target value according to detected value, reference detected value and environmental condition value. SOLUTION: A reference pattern transmitted from an IPU part 11 to a laser diode(LD) 4 and the scanner data on an original are exposed at a specified part on a photoreceptor drum 1 by the LD 4, and a latent image is formed on the drum 1. The latent image is developed to an image by the respective developing devices 8 of a developing unit 6, and the toner sticking amount of the reference pattern is detected by a toner sticking amount sensor 7. A toner concentration control part 13 compares the detected value transmitted from the sensor 7 with the initialized value (default value) of the toner sticking amount experimentally decided in advance, and decides a correction coefficient according to the specified environmental condition when the compared result exceeds a threshold set in advance.  Then, the next target value is decided based on the correction coefficient, the detected value and the initialized value.
