    摘要: A drum cleaning blade for a image transfer type of copying machine which has a rotatable drum provided thereon with a photo-sensitive cylindrical layer in which an electrostatic latent image of an original to be copied is produced and developed by a toner powder. The blade comprises a main sheet-like center portion having a straight lower edge and a pair of side portions from which triangular projections extend forwardly, respectively. The inner edges of the triangular projections are slanted outwardly.The side portions in which the triangular projections are formed are separated from the main portion through cuts.The lower edge as well as the slanted inner edges of the triangular projections are caused to bear on the outer cylindrical surface of the drum thereby to scrape off the toner particles remaining as deposited on the drum surface after the transfer processing of the toner image to a transfer sheet. The inner slanted edges of the triangular projections serve to prevent the toner particles as scraped off from being scattered laterally outwardly from the drum.

    摘要: A drum cleaning apparatus for an electrophotographic copying machine includes a toner image forming drum rotatable about a horizontal axis, a blade for scraping off toner particles deposited on the cylindrical outer surface of the drum, an inclined toner particle guide plate having an upper edge bearing on the outer surface of the drum upstream of the scraping blade as viewed in the rotating direction of the drum and a lower edge positioned at an opening of a toner collecting container, a holding structure for supporting the toner guide plate and mounted swingably on a shaft with play, the shaft extending in parallel with the axis of said drum. Feeble and periodical shocks are applied to the toner guide plate by way of the supporting shaft thereby to promote the sliding down of the toner particles on and along the guide plate into the collecting container to prevent accumulation of the particles on the plate.

    摘要: A roller fixing device wherein a claw member facing a pressure roller is arranged so that the distance between the contact point of a roller and a pressure roller and the top end portion of said claw member be within 6.5 mm on the pressure roller periphery and an angle between a tangential line of the pressure roller at a point where said top end portion of said claw member contacts under pressure with said pressure roller and the upper edge of said claw member be at least 45 degrees. Said roller is a heat roller including a heater therein. An electrophotographic copying machine which comprises: a charge receptor, a latent image forming means for forming an electrostatic latent image on said charge receptor, a developing means for developing said electrostatic latent image, a transferring means for transferring said developed image to a transfer material, and said roller fixing device.
