Image forming method and image forming apparatus



<P>PROBLEM TO BE SOLVED: To provide an image forming method and an image forming apparatus by which the film thickness of developer supplied onto a developer carrier is kept constant with time by preventing the clogging of the groove of a developer supply member. <P>SOLUTION: In the image forming method for forming an image by supplying liquid developer to the developer carrier 20 by the developer supply member with a groove 32, developing a latent image on an image carrier 10 by the developer carrier 20, and transferring the image on the image carrier 10 to an intermediate transfer member 40; developer supply member cleaning sequence that the developer supply member 32 and the developer carrier 20 are driven in a state in which DC bias applied to the developer supply member 32 is made higher than bias applied to the developer carrier 20 is performed when the image is not formed. <P>COPYRIGHT: (C)2008,JPO&INPIT
【課題】 現像剤供給部材の溝の詰まりをなくし、現像剤担持体上へ供給する現像剤の膜厚を経時的に一定にする画像形成方法及び画像形成装置を提供する。 【解決手段】 溝付きの現像剤供給部材32により液体現像剤を現像剤担持体20に供給し、現像剤担持体20により像担持体10上の潜像を現像し、中間転写体40に像担持体10上の像を転写することにより画像を形成する画像形成方法において、非画像形成時に現像剤供給部材32に印可する直流のバイアスを現像剤担持体20に印可するバイアスよりも高くした状態で、現像剤供給部材32及び現像剤担持体10を駆動する現像剤供給部材クリーニングシーケンスを実行することを特徴とする。 【選択図】図8
