ABSTRACT:
A copying apparatus including a transparent glass platen (10) across which documents for copying are moved. On its face remote from that across which documents are moved, the platen carries a layer (11) of a material which has a lower surface resistivity than the glass, and is typically less than 10.sup.9 ohms per square. The conductive layer is electrically connected, for example to ground, so as to remove electrostatic charge from the platen.
