Latest Patents

One of his latest patents is for a porous reusable ZnO electrophotographic element. This innovative element comprises a photoconductive layer containing sensitized zinc oxide particles and two binding agents that are incompatible. The first binding agent is a macromolecular compound with a higher affinity to zinc oxide, while the second binding agent is present in a substantially larger amount. The resulting photoconductive layer is formed of agglomerates of zinc oxide particles, providing a porous structure that enhances its performance in electrophotographic copying machines. Another significant patent involves an electrophotographic process that utilizes double charging to form an electrostatic image on a photoconductive element. This process involves first positively charging the top layer and then negatively charging it until saturation, followed by imagewise exposure to light.
