    摘要： An image forming method wherein a developer layer formed by a layer forming material and supported on a developer supporting body is used to develop an electrostatic latent image on an electrostatic latent image supporting body, thereby forming an image. In the method, the direction of rotation of the developer supporting body is the same as that of the electrostatic latent image supporting body, the ratio of peripheral speed of the developer supporting body to the electrostatic latent image supporting body ranges from 0.7 to 1.8, the developer is composed of a carrier and a toner, and the toner contains a conductive inorganic fine powder. The method is useful for making an amount of static electrification of the toner suitable and stabilizing the same.

    摘要： A carrier for an electrostatic latent-image developer, comprising a core material having thereon a coating layer comprising a resin and fine electroconductive particles, the resin having a work function of 4.5 eV or lower. An electrostatic latent-image developer comprising the carrier and a toner and an image forming process are also disclosed. The carrier is capable of maintaining a high build-up speed of electrification and a proper electrification level even when a charge control agent is omitted or used in a slight amount or when the addition amount of an additive such as silica and titanium oxide is reduced so as to prevent carrier fouling with a charge control agent or an external additive and to inhibit a decrease in developer life.

    摘要： An image forming apparatus performs a stable developing characteristic for an electrostatic latent image including a halftone image expressed by a binary manner. The apparatus includes a photoreceptor having a surface and an electrostatic image forming device for forming an electrostatic latent image on the surface of the photoreceptor, the electrostatic latent image including a digitally-reproduced binary latent image. The apparatus further includes a developing device for developing the electrostatic latent image. The developing device includes a two-component developer including magnetic carrier particles and toner particles. The apparatus also includes a bias applying device for applying a bias voltage between the developing device and the photoreceptor for defining a relatively high contrast potential of the digitally-reproduced binary latent image to be developed. The developing system includes a control system for controlling a certain amount of toner to be developed to be substantially constant corresponding to the contrast potential. Several configurations of the developing device may be adopted to the purpose.
