Abstract

PURPOSE:To obtain good effects of cleaning for magnetic toner and non- magnetic toner by forming a toner collecting part in the cleaning device. CONSTITUTION:The magnetic toner collected in a cleaning device 2 is caught by a magnetic roll 4 and is successively conveyed to the toner storage part in the device with the rotation of the magnetic roll 4. And a control end edge part 5a formed at the tip of a control blade 5 which controls the quantity of the toner which is accumulated on the surface of the magnetic roll 4 is arranged in a forward direction, having a proper distance against the surface of the roll 4. Consequently, a considerable quantity of the toner which is conveyed to the position of the control blade 5 by the roll 4 and the cleaning blade 3 is stored in a void space formed between the end edge part 5a and the roll 4, and the toner overflowing from the void space is discharged by a conveying screw 6.
