A corona discharger that applies a voltage to a wire stretched inside a shield case to perform corona discharge, and uses a suction device to remove ozone generated during corona discharge in the longitudinal direction of the shield case. In a corona discharge device of an electrophotographic printing device that sucks ozone through a ventilation hole provided in the corona discharge device, the ventilation hole is arranged so that the ozone suction force in the longitudinal direction of the corona discharger becomes uniform. A corona discharge device for an electrophotographic printing device, characterized in that the suction portion side is formed wide. 2. The corona discharge device for an electrophotographic printing device according to claim 1, wherein the ventilation hole has a diameter larger on the side opposite to the suction portion from the suction device than on the side opposite to the suction portion.
