PURPOSE:To prevent the titled developing device from the scattering of a developer extremely efficiently and precisely by fitting a conductive member to the back end side of a passage forming plate and arranging a corona discharging wire for discharging corona to the conductive member. CONSTITUTION:An insulated passage forming plate 7 is fitted to the outside of the bottom 1a of a box so that a developer recovering passage 8 is formed along the bottom. A conductive member 9 is attached to the back end part of the passage forming plate 7 and a corona discharging wire 10 for discharging corona to the conductive member 9 is arranged. When corona is discharged from the corona discharging wire 10 to the conductive member 9, the developer led into the passage 8 is sent to the position of the conductive member 9 by the ion wind due to the corona discharge and catched by the conductive member 9, preventing the developing device from developer scattering extremely efficiently and prcisely. |
