Long Life Technologies of OPC in Fuji Xerox

Abstract

Fuji Xerox began full-fledged launch of its own developed organic photoreceptor in the 1990' s, and replaced it with an organic photoreceptor from the selenium inorganic photoreceptor used until then. Since then, in response to the demand for long life of office multifunction printers and printing markets, we have been prolonging the life of photoreceptors, which is the rate-limiting factor of life.

Improvement of undercoat layer with respect to internal factors such as material deterioration, improvement of stress tolerance of the surface layer (charge transport layer/overcoat layer) and improvement of friction coefficient (charge transport layer/overcoat layer) against external factors such as wear/scratch, etc. have been carried out continuously. In this paper, we introduce the history of development of photoreceptors up to now, and the technology of the latest undercoat layer, charge transport layer and overcoat layer.
