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： In an electrostatic photographic process comprising subjecting an electrostatic photographic photosensitive plate to the combination of negative charging, positive charging and imagewise exposure to form an electrostatic latent image of a positive polarity, said electrostatic photographic photosensitive plate having such charging characteristics that a photosensitive layer can be positively charged by sequential negative corona charging and positive corona charging and positive charging is rendered substantially impossible by irradiation with light, and then subjecting the so treated photosensitive plate to positive charging a predetermined number of times, whereby an electrostatic latent image is formed the predetermined number of times by imagewise exposure conducted once, if a zinc oxide-resin dispersion is used for the photosensitive layer of the photosensitive plate and predetermined amounts of a triphenylmethane basic dye and a silicone oil are incorporated in the photosensitive layer, the time required for negative charging can be shortened, and the charge potential at the time of positive charging can be increased and accumulation of the residual potential after irradiation with light can be reduced.

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.
