  • Electrophotographic element and imaging method exhibiting reduced incidence of laser interference patterns
    Patent number: 5403686
    Abstract: Electrophotographic elements including near-infrared radiation absorbing sensitizers and selected near-infrared radiation absorbing additives exhibit a reduced tendency toward the formation of laser interference patterns. These elements can be utilized in electrophotographic imaging processes including the steps of electrostatically charging the element, imagewise exposing the charged element to near-infrared radiation to form an electrostatic latent image, developing the electrostatic latent image by applying charged toner particles to the element to produce a toned image, and transferring the toned image to a suitable receiver.

  • Inverse multiactive electrophotographic element
    Patent number: 5213927
    Abstract: New inverse multiactive electrophotographic elements comprise, in order:an electrically conductive layer;a charge-transport layer;a first charge-generation layer containing a charge-generation material and a charge-transport material; anda second charge-generation layer containing a charge-generation material and a charge-transport material different from and less susceptible to positive-surface-charge injection than the charge-transport material of the first charge-generation layer.
