Abstract
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.
Claims21
A process for manufacturing an organic photoconductive drum comprising:
- sequentially forming on an electrically-conductive substrate comprising a cylindrical support having a predetermined weight an optional dry undercoat layer, a dry barrier layer, a dry charge-generation layer, and a dry charge-transport layer;
- following said forming of each said dry layer, determining the cumulative weights of said cylindrical support and said dry layer(s) sequentially formed on said support;
- using said cumulative weights, determining by subtraction the weight of each said dry layer;
- and
- using previously acquired data correlating weight with thickness for each said dry layer, determining the thickness of each said dry layer.
