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.

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 image-forming machine having a main body and a process unit adapted to be detachably mounted on the main body. The process unit includes a first unit having a developing device and a charging corona discharger and a second unit having a rotating drum and a cleaning device. The developing device comprises a magnetic brush mechanism comprised of a hollow cylindrical sleeve and a permanent magnet disposed within the sleeve and a blade adapted to be brought into press contact with the surface of the sleeve and to decrease sufficiently the thickness of the developer layer on the sleeve surface. The cleaning device includes an elastic blade adapted to be brought into press contact with a photosensitive member disposed on the surface of the rotating drum. The toner removed from the surface of the photosensitive member by the action of the elastic blade is recovered into an interior space of the rotating drum.
