Abstract
PURPOSE:To recover the toner well with simple and small-sized constitution by enabling the recovered toner to be conveyed from a discharge port to a replenishing port by a length of rudder chain of a predetermined angle of inclination covered by a duct provided with a toner-falling-preventing guide. CONSTITUTION:The excess toner in a photosensitive drum 20 is well recovered by a cleaning blade 23, a fur brush 27, etc. contactually touching the drum 20 and is collected near the discharge port by way of an auger 73 etc. This recovered toner is conveyed by a length of rudder chain 84 which is covered by a duct 86 provided with a toner-falling-preventing guide 87 of one body and of which the angle of inclination is less than the angle of repose of the toner. This toner then falls into the replenishing port 76a of a developing device 76 installed in the position upper than the discharge port. Hence, the excess toner well recovered from the photosensitive drum is recovered well and surely into the replenishing port of the developing device without returning into the discharge port of the recovery device by the simple and small-sized constitution.
