WASTE TONER CONVEYANCE EQUIPMENT, CLEANER, PROCESS CARTRIDGE, IMAGE FORMING DEVICE, AND ELECTROPHOTOGRAPHIC EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To efficiently carry out conveyance when conveying a recovery container of waste toner, and to prevent clogging and toner blocking of a conveyance path due to toner accumulation.;SOLUTION: Waste toner scraped off from a surface of an image carrier by a cleaning blade is accumulated in a container 29 of the cleaner 26. A conveyance coil 33 is rotatably provided for conveying the waste toner in a longitudinal direction. The conveyance coil 33 is comprised of an upstream side coil 33a and a downstream side coil 33b, and each coil 33a, 33b is machined such that rotation centers are different. Since the waste toner is accumulated and fixed from a conveyance direction downstream side when a whole of the conveyance oil is rotated, and by machining the conveyance coil 33 in such way, the toner accumulated in the downstream side is agitated by rotation of the coil, it can be conveyed while loosening it, and the waste toner can be efficiently conveyed without causing clogging or toner blocking.;COPYRIGHT: (C)2010,JPO&INPIT
