摘要： It is an object of the invention to provide a dielectric drum where manufacturing costs can be reduced while keeping pressure resistance high and having an anodic oxidized film with a uniform dielectric characteristic, and also to provide an electrostatic recording device which is inexpensive and provides a high image reliability using the dielectric drum. According to the present invention, a dielectric drum includes an aluminum substrate and a dielectric layer of an anodic oxidized film on the surface of the aluminum substrate. The aluminum substrate is produced by conducting a drawing and hardening treatment M on an aluminum alloy pipe of the 5000 series alloys of the Aluminum Association. Also, the dielectric drum is used to construct an electrostatic recording device. The electrostatic recording device includes toner image forming means for forming a toner image on a dielectric drum, and pressure applying means for transferring by pressure or transferring and fixing by pressure the toner image on the dielectric drum to a member to be transferred.

摘要： A recording member comprising a conductive substrate having a dielectric coating thereon. The recording member is particularly useful with the electrographic recording process and apparatus described in U.S. Pat. No. 3,816,840. The dielectric coating exhibits charge dissipation properties that will allow removal and replacement of toner powder within one operating cycle of the aformentioned recording process, and the surface of the coating is sufficiently durable to allow the recording member to be used repeatedly, e.g., at least about 20,000 cycles, before the conductive substrate needs to be recoated.

摘要： A process for producing an electrostatic recording material which comprises kneading a hydrophobic pigment having a critical surface tension of 50 dynes/cm or less with an aqueous dispersion of a copolymer consisting of (I) 10 to 50% by weight of methacrylic acid, (II) 5 to 50% by weight of a alkenyl aromatic compound and (III) 30 to 85 % by weight of at least one member selected from the group consisting of conjugated diolefins, alkyl acrylates and alkyl methacrylates; having a glass transition temperature (Tg) of 40.degree. C or less; and having an intrinsic viscosity [.eta.] of 0.1 to 1.0 dl/g as measured in tetrahydrofuran at 25.degree. C, in a weight ratio of the copolymer to the pigment of 100/20 to 100/200, in the presence of an alkaline material in such a proportion that the viscosity of the aqueous dispersion of the copolymer becomes at least 350 cps, adjusting the viscosity of the aqueous dispersion containing the copolymer and the hydrophobic pigment to 10 to 5,000 cps, coating the resulting coating composition on the surface of an electroconductive base sheet and drying the same. Said process can produce, with a high production efficiency, an electrostatic recording material having a substantially glossless appearance like ordinary paper of office use, being excellent in writability with a pencil and an aqueous ink, stampability and printability, and being capable of recording clear copy images thereon.
