Abstract
An electrically-conductive support for an electrophotographic medium, comprising a support and an electrically-conductive layer provided on the support is disclosed. The electrically-conductive layer comprises a binder and electrically-conductive metal oxide fine particles having an average grain size of 0.5.mu. or less, dispersed in the binder.
Claims6
An electrically-conductive support for use in an electrophotographic medium, comprising:
- a support;
- and an electrically-conductive layer provided on the support wherein the electrically-conductive layer comprises a binder and electrically conductive metal oxide fine particles having an average grain size of 0.5.mu. or less and a volume resistivity of 10.sup.6 .OMEGA.-cm or less, dispersed in a binder, wherein said electrically-conductive metal oxide fine particles are selected from the group consisting of crystalline metal oxide particles and metal oxide particles containing an oxygen deficiency or small amounts of hetero atoms capable of forming a donor for the metal oxide used, wherein said electrically-conductive support is transparent such that it has a transmittance of light, having a wavelength range including visible light, of about 50% or more, and a light-scattering efficiency of about 50% or less.
