PURPOSE: To obtain a picture with high resolution by pressure-fixing a recording element having a tonor image obtained by charging and inversion development on its recording layer after subjecting AC corona discharging or reversed corona discharging to said charging.

CONSTITUTION: A recording element consists of a supporting element with a conductive surface and a photoconductive layer formed on the surface of the supporting element. If necessary, a transparent insulated layer is permitted to be formed on the photoconductive layer. Said photoconductive layer is charged, e.g., negatively by corona discharging at a dark place and exposed through a negative film to form an electrostatic latent image. Subsequently inversion development is performed to obtained a positive tonor image. By fixing the surface of the recording element after discharging the charge on the surface by AC corona or reversed polar corona discharging, a clear fixed tonor image can be obtained.
