Elastic developer carrier |
摘要 |
An elastic developer carrier for use in a developing device for developing an electrostatic latent image formed on a photosensitive member includes an electrically conductive support, a rubber magnet layer formed on the support and magnetized in a desired pattern having alternating N and S poles, and an electrode layer formed on the rubber magnet layer having a plurality of electrode particles electrically isolated from one another and partly exposed at its outer surface. In another embodiment, an intermediate dielectric layer is provided as sandwiched between the rubber magnet and electrode layers. These developer carriers may be made much lighter in weight and used with a relatively hard photosensitive member without causing a deterioration in developing performance. Novel processes for fabricating these developer carriers are also provided.
