An electrophotographic recording sheet having a bichargeable photoconductive layer extending over a sheet substrate including as photoconductive pigments in the layer a blend of photoconductive zinc oxide and photoconductive titanium dioxide, the titanium dioxide comprising from 20 to 70 percent of such blend and the zinc oxide comprising at least 20 percent of the blend. These impart to the sheet a positive and a negative charge acceptance exceeding 350 volts, and a positive and a negative light sensitivity value of less than 120 footcandle-seconds.
