    摘要: A cleaning device for use on a transfer type electrostatic copying apparatus includes a magnetic brush cleaning device for cleaning off a magnetizable toner remaining on a photosensitive material after a transfer operation. A brush roller is disposed between the magnetic brush cleaning device and a transfer zone. A brush is arranged on a peripheral surface of a cylindrical sleeve of light transmitting material and is driven for rotation in contact with the photosensitive material. A charge eraser lamp is secured within the cylindrical sleeve. The charge on the photosensitive material or photoreceptor is almost completely erased, and consequently, the cleaning efficiency is markedly improved owing to the facilitated removal of the developing material by the magnetic brush.

    摘要: An apparatus for developing a latent electrostatic image, includes a developer holding member having a surface adapted for movement through an endless path and a developer receptacle having an opening formed at a site opposite to a part of the endless path. The receptacle contains a one-component developer consisting only of toner particles capable of retaining an electric charge. The developer in the receptacle is held on the surface of the developer holding member and charged by a charging member. The charged developer is carried to a developing zone by the movement of the surface of the developer holding member and applied to a latent electrostatic image to be developed.

    摘要: An electrostatic copying machine apparatus includes a developing device having a fixedly positioned permanent magnet and a hollow developing sleeve formed of a non-magnetic material mounted coaxially about the permanent magnet for rotation thereabout. Toner supplied to the periphery of the sleeve forms thereon a magnetic brush which is conveyed by rotation of the sleeve to a developing position whereat the toner is transferred to a photoreceptor as a visible toner image. A bristle cutting member is positioned upstream of the developing position to restrict the length of the magnetic brush. A blade member formed of a non-magnetizable material prevents solidification of the toner on the periphery of the sleeve and is positioned upstream of the bristle cutting member. The blade member slides in contact with the periphery of the sleeve at a scraping position. The permanent magnet has spaced therearound at equal circumferential intervals a plurality of magnetizing positions having magnetic poles. One pole is at a first magnetizing position confronting the bristle cutting member, and another pole is at a second magnetizing position confronting the scraping positions. These two poles are of opposite polarities and are adjacent to each other. At least one magnetizing position includes a pair of poles of the same polarity.

    摘要: A photosensitive drum assembly for an electrostatic copying apparatus includes a cylindrical drum having a photosensitive layer provided around its outer periphery. The drum is held between a pair of flanges at opposite axial ends of the drum. Each of the flanges is formed having a diameter larger than the external diameter of the drum. At the edge of each flange, is a cylindrical portion extending along the axis of the drum to face toward the opposite flange. The end edges of the drum closely fit into the cylindrical portions. According to the present invention, since the edges of the drum closely fit into the cylindrical portions of the flanges, it is not necessary to improve the dimensional accuracy of the inside periphery of the opposite ends of the drum, while it is essential to improve the dimensional accuracy in a conventional manner.

    摘要: A copying apparatus provided with a cassette-type paper feeding mechanism. The paper feeding mechanism includes a cassette-receiving section disposed at an upstream end of a paper transfer passage defined within a housing and a copying paper cassette to be mounted to the cassette-receiving section through an opening formed in a side wall of the housing and is constructed such that when the paper cassette is inserted into the cassette-receiving section through the opening of the housing to set it at an inoperative position and further moved in a predetermined direction to set it at an operative position, a paper feeding member provided in the cassette-receiving section acts on a copying paper in the paper cassette to render it ready for feeding into the paper transfer passage. A pair of paper transfer rollers are provided at that position of the paper transfer passage which is in proximity to the cassette-receiving section, and at least one of these transfer rollers is mounted movably relative to the other. When the paper cassette is set at the operative position, said one transfer roller is in contact with said other transfer roller, but when the paper cassette is moved from the operative position to the inoperative position, the movement of the cassette is transmitted to said one transfer roller through a motion-transmitting member thereby to separate said one transfer roller from said other transfer roller.
