PURPOSE:To prevent a copy form and a fixing device from being stained with a releasing agent by forming a proper number of releasing agent through holes at proper positions of a blade supporting member which supports an elastic rubber blade as a cleaning blade. CONSTITUTION:The upper end part of the elastic rubber blade 5 is inserted into the recessed groove part 7 of the blade support member 6 made of metal, etc., in one body, and through holes 8- piercing said elastic rubber blade 5 are bored at proper positions of the recessed groove part 7 of the blade support member 6. Consequently, when a heat roll 10 is cleaned, the releasing agent which almost stays in front of this elastic rubber blade 5 is discharged from in front of the blade 5 to an oil supply wick behind it through said through holes 8-. Therefore, no releasing agent stays in front of the blade 5 and the copy form and fixing device are prevented from being stained with the releasing agent. |
