<p>In a process for manufacturing an organic photoconductive drum there is sequentially formed on an electrically-conductive substrate that includes a cylindrical support of known weight the following layers: an optional dry undercoat layer, a dry barrier layer, a dry charge-generation layer, and a dry charge-transport layer. Following the formation of each dry layer, the cumulative weights of the cylindrical support and the dry layer(s) sequentially formed on the support are determined. Using the cumulative weights, the weight of each dry layer is determined by subtraction. The thickness of each dry layer is then determined, using previously acquired data correlating weight with thickness for each dry layer.</p> |
