Abstract
Electrostatic recording apparatus forming small non-recording regions in a recording field includes a beam generator generating a beam modulated with a modulation signal, an irradiating unit directing the beam to a photosensitive member to form an electrostatic image, a determination circuit determining when the electrostatic image formed by the beam on the photosensitive member exceeds a predetermined size, an interruptor for intermittently interrupting the emission of the beam at small time intervals, and an actuating circuit actuating the interruptor when the determination circuit determines when the electrostatic image exceeds the size.
