An image forming apparatus includes an image forming device for forming an image on a recording material, the image forming device having a contactable member which is contactable with the recording material with electrostatic attraction force between the contactable member and the recording material; a separation discharger for electrically discharging the recording material upon separation of the recording material from the contactable member after image formation on the recording material, the separation discharger having a wire electrode and a shield electrode; wherein Vp/f</=0.5 is satisfied where Vp is a conveying speed of the recording material (mm/sec), and f is a frequency of a periodically changing voltage applied to the separation discharger (Hz), wherein the inside of the shield electrode is reduced toward the contactable member.
