发明名称 TONER AMOUNT DETECTING DEVICE
摘要 PROBLEM TO BE SOLVED: To obtain a device whose constitution is simple, whose cost is low and which does not erroneously detect toner amount by detecting toner amount based on the moving amount of a toner pushing-out means from the position of the toner pushing-out means before toner supply to the position thereof after the toner supply. SOLUTION: A toner pushing-out panel 2 and a toner pushing-out panel driving part 4 are installed in a replenishing chamber 10a. A pushing-out panel position detection part 5 detecting the position of the panel 2 driven to be rotated by the driving part 4 is provided in the chamber 10a. The panel 2 driven by the driving part 4 is moved and the specified amount of toner is supplied from the chamber 10a to a supply chamber 10b. Then, the toner amount is grasped by the detection part 5 as the moving amount of the panel 2, that is, the moving amount from the position of the panel 2 before the toner supply to the position thereof after the toner supply.
