Abstract
A transfer material carrying member is described which has at least two resin-containing layers. The relative dielectric constant (E1) of the surface layer and the relative dielectric constant (E2) of the layer(s) other than the surface layer show a ratio (E1/E2) satisfying the following expression of 0.02.ltoreq.(E1/E2).ltoreq.0.7. The carrying member shows a high transfer efficiency and is able to provide high quality images for a prolonged period of time.
