摘要： A thick organic ambipolar layer on a photoresponsive device is simultaneously capable of charge generation and charge transport. In particular, the organic photoresponsive layer contains an electron transport material such as a fluorenylidene malonitrile derivative and a hole transport material such as a dihydroxy tetraphenyl benzadine containing polymer. These may be complexed to provide photoresponsivity, and/or a photoresponsive pigment or dye may also be included.

摘要： An endless flexible seamed belt with a mechanically and electrically invisible seam, substantially equivalent in performance to a seamless belt, is formed by joining two ends of substrate material, each end of which has a plurality of mutually mating elements in a puzle cut pattern which are in interlocking relationship. After the two ends are joined, an bonding is applied to the seam of the belt. When the belt is to be an electrostatographic imaging member, the electrostatics of the belt become very important. The two ends of a flexible substrate with a conductive coating applied thereto are interlocked and a conductive bonding is applied to the gap between the interlocking surfaces. The undercoating layer can then be applied to the adhered seam in order to smooth the seamed surface for application of the charge generating layer and the charge transfer layer. The undercoating layer may be relatively thicker than current undercoating layers to insure that the seam surface is smooth.
