Overwiev of the Surface Conditions of the Photoconductors by the Image Analysis Method

Electrophotography, as the technique of the digital printing process is more and more present. Photoconductors in electrophotography are exposed not only to the mechanical activity because of the pressure of the printing form on the printing substrate but to the IR radiation by LED laser and to electrical charging which appeared in the developing phase. The changes of the photoconductor surface in relation to the number of prints have been investigated in this work. The suitability of the image analysis application as the method for observing the changes of the organic photoconductors has been discussed. Durability of the photoconductors and the observing the damages in its surface is very important from the point of view of print quality and economy of the printing process.
