PROBLEM TO BE SOLVED: To lubricate a second toner eliminating scraper blade satisfactorily by providing a grain conveying means between a plurality of grain eliminating members for eliminating grain from a cleaning means, at the center along a centerline. SOLUTION: A first brush 100 is biased to polarity unlike the greater part of toner 102 so as to take away the greater part of the toner 102 from a photoreceptor 10. A second brush 120 on the lower reaches is biased to polarity unlike the first brush 100 so as to eliminate the toner 102 charged to wrong polarity from the photoreceptor 10. An auger assembly 110 is disposed in a passage between toner eliminating rollers 105, 120 and slightly behind a centerline connecting the rollers 105, 120. The remaining toner 102 therefore falls down directly on the upper part of an auger channel from the first toner eliminating roller 105, and the lubrication of a scraper blade 126 on a second toner eliminating roller 125 is positively performed by opening the bottom part of the auger 110. |
