Abstract
Abstract An electrostatic image-bearing dielectric member comprises a support and a dielectric layer formed on the support. The dielectric layer is formed of at least one of amorphous carbon, diamond-like carbon and diamond. The dielectric layer may contain not larger than 60 atomic percent of at least one of hydrogen and fluorine. An intermediate layer may be provided between the support and the dielectric layer in order to improve the adhesion therebetween.
