Zusammenfassung:To provide a developing method and an image forming apparatus that can recover a residual toner by using a developing roller, while preventing filming on a surface of a photoconductor drum.SOLUTION: A developing method includes the steps of: supplying, with a developing roller 8, a non-magnetic one-component negatively charged toner from a housing 7 to a photoconductor drum 4 (S1); transferring, with a transfer roller 9, the toner on a surface of the photoconductor drum 4 to a sheet S (S2); peeling, with a peeling roller 21, a residual toner T attached to the surface of the photoconductor drum 4 from the surface of the photoconductor drum 4, and attaching the peeled residual toner T to the surface of the photoconductor drum 4 (S4); charging, with a charging roller 5, the surface of the photoconductor drum 4 to which the residual toner T is attached (S5); and recovering, with the developing roller 8, the residual toner T into a housing 7 (S8).SELECTED DRAWING: Figure 3 【課題】感光ドラムの表面のフィルミングを抑制しつつ、現像ローラを用いて、残トナーを回収できる現像方法および画像形成装置を提供する。【解決手段】現像方法は、現像ローラ8により、非磁性一成分系の負帯電性トナーを筐体7から感光ドラム4へ供給する工程(S1)と、転写ローラ9により、感光ドラム4の表面のトナーをシートSへ転写する工程(S2)と、剥がしローラ21により、感光ドラム4の表面に付いた残トナーTを感光ドラム4の表面から剥がし、剥がした残トナーTを感光ドラム4の表面に付ける工程(S4)と、帯電ローラ5により、残トナーTが付いた感光ドラム4の表面を帯電させる工程(S5)と、現像ローラ8により、残トナーTを筐体7へ回収する工程(S8)とを含む。【選択図】図3
