Abstract
Azine derivatives or their combinations with hindered phenol antioxidant in the charge transport layer containing one or more triarylamines or a combination of one triarylamine and one hydrazone improve light fatigue of a photoreceptor, which results in stabilized print quality. The robust performance against light damage allows the shutter in a cartridge to be removed and the requirement for special protection procedure during inspection and handling to be simplified.
