CLEANING BLADE FOR DRUM OF ELECTROPHOTOGRAPHIC COPIER

摘要

PURPOSE:To effectively prevent the scattering of toner particles outwardly at both sides by a simple structure comprising a triangular end portion protruding gradually downwardly according as it faces outwardly attached to both lower side edges of rectangular cleaning blade, the former integrally formed with the latter. CONSTITUTION:Two end portions 2B, 2B of trianaular shape which have an oblique lower edge 8 protruding gradually downwardly a ording as it faces outwardly are integrally formed with both lower side edges of straight lower edge 3 of the main part 2A of rectangular drum cleaning blade 2, respectively. It is arranged that the inner ends of oblique lower edges 8 of these two end portions 2B, 2B are in contact with the lower edge 3 of the main part 2A. Notches 9, 9 which extend upwardly from the inner end position are formed. and the central portion 2C with straight lower edge 3 and two side portion 2D, 2D with the oblique lower edges 8 are partitioned by the notches 9, 9. The blade 2 is held by holder 4 to press the lower edges 3, 8 of the blade 2 onto the outer circumference of the drum 1.
