Title: Image density controller for image recorder
Inventor: KANEDA MASAYUKI
IPC: G03G15/08
Filed: 2000-01-27
Abstract: PROBLEM TO BE SOLVED: To accurately maintain image density by successively adding stored toner replenishing time and performing replenishment of toner only for a prescribed time when the added toner replenishing time is equal to or longer than the prescribed time. SOLUTION: Reflected light obtained at irradiating of a reference reflector 2 by the scanning of an exposing lamp 3 is read by an AE sensor 32 and reflected light obtained at the time of scanning an original surface is detected, and the area coverage of an original is calculated by a controller 30, based on the ratio of the reflected light. Then, the on-time of a dispense motor is calculated and integrated, by assuming that toner consumption equivalent to the calculated area coverage of the original exists. Every time the integrated time exceeds 500 mm/sec, for example, the dispense motor is driven to supply the toner by setting 500 mm/sec as the units. When the toner replenishing time is less than a prescribed time, it is successively added without replenishing the toner.  When the added toner replenishing time is equal to or longer the prescribed time, the toner is supplied only for a prescribed time.
