ABSTRACT:
The present invention discloses a conductive substrate applicable to electrostatic recording processes, electrophographic processes and the like, and demonstrating excellent resistance to damage by high or low relative humidity.
A conductive substrate according to the present invention is characterized by having an improved-conductive layer with over 10.sup.8 ohm/.quadrature. of an electrical sheet resistivity thereof which is stable in a high or low relative humidity and other environment factors, and which is prepared by blending a carbon black with at least one of the other types of electronic conductive materials except the carbon black in proportion of from 10 to 100 parts of the material per 100 parts by weight of the carbon black.
