发明名称 SHEET SEPARATING DEVICE, FIXING DEVICE, AND IMAGE FORMING APPARATUS
摘要 <P>PROBLEM TO BE SOLVED: To accurately maintain the positional relation between a nozzle member and a fixing member, wherein the nozzle member blows compressed gas at the gap between a fixed sheet material and the fixing member so as to separate the sheet. <P>SOLUTION: The sheet separating device 70, in a fixing device 60 which is provided with a fixing roller 64, a fixing belt 61, and a pressing roller 62, and conveys the sheet material P supporting unfixed toner through a nip section N, includes the nozzle member 80 that discharges the compressed air from the direction of a nip outlet toward the nip section N direction along the fixing roller 64. The nozzle member 80 is arranged such that the size of the narrowest area of clearance between the nozzle member 80 and the fixing roller 64 and between the nozzle member 80 and the fixing belt 61 is equal to or less than 2.0 mm. The nozzle member is rotatably supported by a shaft member 90 that is provided parallel to the fixing roller 64, and includes a gas flow passage 91 through which the compressed air is supplied to the nozzle member 80. <P>COPYRIGHT: (C)2013,JPO&INPIT
