PURPOSE:To prevent the contamination in a body by providing an auxiliary toner collecting box which can oppose to the lower part of a blade cooperatively with the removing operation of a photoreceptor. CONSTITUTION:When a photoreceptor 2 is in a home position, a blade 3 presses its bottom end edge to the surface of the photoreceptor, thereby scraping off the remaining toner. A hermetically closing roller 4 carries out the toner by revolving reverse in contact with the surface of the photoreceptor 2. The toner is scraped off from the surface of the roller 4 by a scraper 5 and is contained into a toner collecting box 6. At the same instant when the photoreceptor 2 is removed from the body, an oscillating arm 8 is turned by the force of a spring 11 to oppose an auxiliary toner collecting box 13 to the lower part of the blade 3, so that the spilling toner (b) is contained in this box 13, thereby preventing the body of the copying machine from being stained. When an opening and closing plate 13 is pulled in the home position and the bottom part of the box 13 is opened, the toner in the box 13 is released into the box 6. |
