Abstract (en)
[origin: EP0491315A1] 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; and a 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.
