Abstract
An electrostatic reproducing apparatus, in which the ion flow passing through an ion modulating electrode and reaching a reproducing member is increased by strengthening the electric field between the electrode of the ion modulating electrode and the reproducing member. Ion transmissive apertures formed in the ion modulating electrode is made to have a larger diameter at its ion outlet than at its ion inlet so that the ion transmission factor may be improved. Condenser electric field generating means such as an electrode for generating an electric field to converge the ion flow toward the ion transmissive aperture of the ion modulating electrode is mounted on the common electrode of the ion modulating electrode at its inlet so that the ion flow of the ion generator using the corona wire may be highly dense.
