| description | To provide an image forming apparatus that can supply a necessary amount of toner to a contact part of a cleaning blade and an image carrier surface and thereby can maintain cleaning performance.SOLUTION: An image forming apparatus comprises: an image carrier 21 that has an image carrier surface 21a for carrying a toner image formed with an electrified toner; a transfer device 24 that applies an electric charge having a polarity opposite to that of the electrified toner through a sheet-like medium S to transfer the toner image on the image carrier surface to the sheet-like medium; a cleaning device 26 that scrapes off and removes, with a cleaning blade 26a, a residual toner not transferred to the medium and remaining on the image carrier surface; and a discharge device 40 that discharges the electric charge having a polarity opposite to the electrified toner to the image carrier surface immediately before the toner image is transferred to the medium.SELECTED DRAWING: Figure 1
【課題】クリーニングブレードと像担持面との当接部に必要量のトナーを供給することが可能で、これによりクリーニング性能を維持することが可能な画像形成装置を提供する。【解決手段】帯電したトナーによるトナー画像を担持するための像担持面２１ａを有する像担持体２１と、シート状の媒体Ｓを介して帯電したトナーに対する逆極性の電荷を印加することにより、像担持面上のトナー画像をシート状の媒体に転写する転写装置２４と、媒体に転写されずに像担持面に残った残留トナーをクリーニングブレード２６ａでそぎ取って除去するクリーニング装置２６と、媒体にトナー画像を転写する直前の像担持面に対して、帯電したトナーに対する逆極性の電荷を放電する放電装置４０とを備えた画像形成装置である。【選択図】図１ |
