    Abstract: An electrostatic recording apparatus includes a developing agent carrying member (15) having a surface for carrying a developing agent thereon. A plurality of recording electrodes (20a) are arranged on the surface of the developing agent carrying member (15) in parallel to each other at a predetermined gap while being electrically insulated from each other. An electrode cylinder (5) is arranged to oppose the plurality of recording electrodes (20a) at a predetermined gap. A developing agent convey section (14) conveys the developing agent such that a circulating convey path is formed along the surface of the developing agent carrying member (15). A voltage control section (C) outputs a control signal including recording data. A recording electrode drive section (21) is provided inside a space defined by the circulating convey path. Upon reception of the control signal from the voltage control section (C), the recording electrode drive section (21) applies a recording voltage to the plurality of recording electrodes (20a) in accordance with the recording data, and selectively transfers the developing agent conveyed by the developing agent convey section (14) to the electrode cylinder (5), thereby forming a recording image.
