PURPOSE:To effectively prevent the generation of toner staying near an inlet seal of a casing lower part by the residual toner removed from a photoreceptor surface by a cleaning blade and fallen to the lower part of the casing. CONSTITUTION:An air inlet port 28 is provided between a toner recovering coil 22 and an inlet seal 21, one end of a supply pie 29 is connected to the air inlet port 28, and the other end of the supply pipe 29 is connected to the air outlet port of an air compressor 19. Air is sent along the inlet seal 21 by the air blown out from the air compressor 19 to prevent the toner scraped by a cleaning blade 18 from being accumulated in the cleaning inlet part to cause toner staying. |
