Title:
ELECTROSTATIC RECORDING MEDIUM
Document Type and Number:
Japanese Patent JPS5528022
Kind Code:
A
Abstract:

PURPOSE: To use a high-resistance plastic film as a base material because of repetitive use, improve the strength of the electrostatic recording medium and further prevent the same from being affected by transfer corona by providing a conductive material on the exposed portion of the low resistance layer.

CONSTITUTION: Metal is evaporated on an insulation type base material, e.g., a polyester film 1 of 100μm thick, and a low resistance layer 2 having surface resistance of 1×106 to 1×103Ω/square is provided thereon. A recording layer 3 having surface specific resistance of 1012 to 1016Ω is provided thereon so as to expose part of the entire circumference of the layer 2. Next, a conductive layer 4 of surface resistance 5×105Ω/square is provided on the exposed portions of the layer 2.
