摘要： An electrophotographic imaging member is improved in light shock resistance by including in the charge transport layer a light shock resisting additive of triethanolamine, morpholine, an imidazole or mixtures thereof. The imaging member preferably has a charge generating layer containing hydroxygallium phthalocyanine, alkoxygallium phthalocyanine and mixtures thereof as the photogenerating particles. The method of rendering an imaging member including such a charge generating layer acceptably resistant to light shock includes forming a charge transport layer in association with the charge generating layer to contain the light shock resisting additive of triethanolamine, morpholine, an imidazole or mixtures thereof.

摘要： An apparatus and associated method for controlling the velocity of the photoreceptor within a reprographic machine having a seamed, web type photoreceptor, for producing a plurality of images thereon. The images being separated by unexposed interdocument regions on the photoreceptor. The reprographic machine further including a registration apparatus for registering copy substrates with developed latent images. The process of assuring that the seamed region of the photoreceptor lies within an interdocument region begins by first sensing an actual phase relationship between the photoreceptor seam and the activity of the registration apparatus and then calculating a phase error value by comparing the actual phase relationship to a desired phase relationship. Next, the system determines an adjustment photoreceptor velocity as a function of the phase error. Subsequently, the photoreceptor is moved at a fixed velocity during exposure of the images. Changing the calculated reference and hence photoreceptor velocity is restricted to the interdocument zone, so that there are no velocity changes except when the interdocument zone is passing through the imaging station. This ensures that the registration requirements and image quality specifications are simultaneously accomplished.

摘要： Correction of image distortion in a reproduction machine due to vibrational or speed distortions in or between a moving photoreceptor and an imaging device projecting raster lines on the photoreceptor as it moves past the imaging device, utilizing in encoder for sensing the speed of the photoreceptor and also the relative vibrational motion between the photoreceptor and the imaging device and providing electrical signals to a signal separator separating the electrical signals into lower and higher frequency signals, and a servo motor for driving the photoreceptor and compensating for the lower frequency increases or decreases in the speed of the photoreceptor, the servo motor being driven by the separated lower frequency signals; and an optical system for pivoting the projected raster lines to compensate for the image distortions which are of the higher frequencies, the optical system being driven by the higher frequency signals from the signal separator.
