Abstract

The instant invention pertains to fabricating a plastic photoreceptor substrate by dip coating. The dip coating process would involve dipping a mandrel into liquid plastic. The substrate may be in the form of for example a drum or a belt. An embodiment of the instant invention is to use a mandrel which is longer than necessary so that the substrate formed on the mandrel can be made longer than required. This extra length may be used to hold the substrate during subsequent processin steps and would be cut off, cleaned,

uniform wall thickness is formed on enough of the substrate so that, when cut to the desired length, the remaining substrate has a uniform wall thickness. The substrate is separated from the mandrel and the mandrel may be reused. The separation can occur before or after the subsequent substrate coating steps. The method of separation of the substrate from the mandrel may depend on the type of plastic used. Preferably, the substrate is separated from the mandrel by relying on the difference in thermal coefficient of expansion between the plastic substrate and the metal mandrel.

Any suitable plastic material including a thermoplastic material and a thermoset plastic material may be employed for the...
