摘要:
An imaging process including providing an electrophotographic imaging member including a substrate, a charge generating layer and a charge transport layer including a small molecule hole transporting diarylamine, a small molecule hole transporting tritolyl amine and a film forming binder, depositing a uniform electrostatic charge on the imaging member with a corona generating device to which power is being supplied, the corona generating device comprising at least one bare metal wire adjacent to and spaced from the imaging member, exposing the imaging member with activating radiation in image configuration to form an electrostatic latent image, developing the latent image with marking particles to form a toner image, transfering the toner image to a receiving member, repeating the depositing, exposing, developing, transfering steps, resting the imaging member for at least 15 minutes under the corona generating device while the power to the corona generating device is removed and while the corona generating device is emitting sufficent effluents to render the surface region of the electrophotographic imaging member underlying the corona generating device electrically conductive if the tritolyl amine were replaced with the small molecule hole transporting diarylamine, supplying power to the corona generating device, and repeating the depositing, exposing, developing, transfering steps at least once.
