PURPOSE:To reduce noises and suppress a scatter of waste toner by giving an impact and vibrating a waste toner container when a waste toner detection signal is sent out. CONSTITUTION:A sensor 39 generates an output according to whether recovery toner cuts off optical path from a lamp 38 or not, and its output is compared by a comparator 117 to detect whether the container is full of waste toner or not. When so, a waste toner container impact signal, i.e. an output to a solenoid 36 is turned on through a CPU101 and a driver 105. At the same time, the clock incorporated in the CPU101 is permitted to start counting the time, and the waste toner container 19 is given an impact for a time long enough to flatten the toner. Thus, continuous vibrating sound is made into intermittent vibrating sound, so noises are reduced and a scatter of waste toner is suppressed. |
