PURPOSE:To remove remaining toner from the surface of a movable electrophotographic receptor without giving any damages to the receptor surface by making a surface which contacts with the surface of the receptor of an elastic blade which removes the remaining toner from the receptor surface to contain a layer in which fine spherical particles of a fluorocarbon resin are buried. CONSTITUTION:Fine spherical particles 8 of a fluorocarbon resin, such as spherical polyvinylidene fluoride resin, etc. having an average primary particle size of 0.1-1mum are scattered on a photosensitive drum 1 and an accumulation 9 of the particles 8 is formed by rotating the drum 1 in the direction shown by the arrow by 10-500 revolutions with an elastic blade 3 made of polyurethane elastomer, etc., being contacted with the drum 1 surface, and then, the particles 8 or their secondary particles are burried and held, by the means which the particles 8 are made to bury into the end part 4 of the blade 3 the shearing force caused by the relative movement between the drum 1 and blade 3 and so forth. Therefore, the remaining toner can be removed effectively without giving any damages to the drum surface and, consequently, not only the life of drum, but also the life of blade can be extended. |
