摘要： PROBLEM TO BE SOLVED: To provide a cleaner that removes toner remaining on a surface of an image holder of an image forming apparatus, wherein an amount of toner remaining in a periphery of a cleaning blade does not become excessive. SOLUTION: A hollow 62 is formed in an outer peripheral edge portion of a spiral blade 56 of an auger screw for conveying toner. When toner dammed by a dam seal 60 becomes excessive and the dam seal deforms, a periphery of an end thereof comes into contact with the outer peripheral edge portion of the spiral blade 56 of the auger screw and the dam seal bends. When the hollow 62 comes to a position opposed to the dam seal as the auger screw 54 rotates, the dam seal falls in the hollow 62 to extend. As the auger screw rotates, the dam seal exits from the hollow to come into contact with an arcuate part of the outer peripheral edge portion of the spiral blade, which is repeated after that. Through the vibration, excessively gathered toner flows out. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus having an environment information measuring means for measuring environment information (temperature and humidity) near an image forming means (image carrier). SOLUTION: An environment measurement sensor 60 is disposed downstream from the end of a photoreceptor drum 11 in an air passage 50 and above the photoreceptor drum 11. The downstream part of the air passage from the photoreceptor drum 11 in the direction of air flow is a place where air warmed by the photoreceptor drum 11 passes. On account of the behavior of heat to elevate, a place above the photoreceptor 11 is the place where heat is transferred without being affected by cooling when a current of air in the air passage 50 is directly blown to the environment measurement sensor 60. Accordingly, the environment measurement sensor 60 accurately measures environment information (temperature and humidity) around a drum cartridge 10 (photoreceptor 11). COPYRIGHT: (C)2010,JPO&INPIT
