Title: Cleaning device of electrophotographic copying machine
Inventor: TSUKAHARA SUMIO
IPC: G03G21/10
Filed: 1982-07-14
Abstract: PURPOSE:To prevent toner staining by providing a beltlike blade which scrapes toner particles remaining on the surface of a photosensitive drum and a channel- shaped holder for clamping and holding one breadthwise end of the blade. CONSTITUTION:A cleaning device is equipped with the beltlike blade 11 for scraping toner particles remaining on the surface of the photosensitive drum and the channel-shaped holder 112 for clamping and holding one breadthwise end of the blade 11. When the edge of the blade 11 is rugged against the surface of the photosensitive drum which rotates as shown by an arrow, the blade deforms elastically and almost linearly on the whole or deforms elastically a little bit less at both lengthwise ends than at the center. Consequently, even the toner particles remaining on the surface of the photoreceptor at both ends are scraped off securely and toner staining is prevented.
