Abstract
The penetration of the digital printing machines using the electrophotographic process into a production printing market is expanding. Along with this trend, further improvements in resolution and reliability are requested to an organic photoreceptor. In particular, a demand for long life is escalating because of the viewpoint of print cost. Recently, highly durable organic photoreceptors incorporating an overcoat layer, based on hybrid material, have been developed. In this report, I would like to explain the overcoat technology of the organic photoreceptor as a successful application of the hybrid material for practical use, and to introduce the latest trends of development in each manufacturer.
