Summary:PROBLEM TO BE SOLVED: To provide a developing device that suppresses the occurrence of a phenomenon where a toner is adhered to a non-image part (fogging) that occurs after low-density images are repeatedly output.SOLUTION: There is provided a developing device including: a developing part that stores a first developer containing a first negatively-charged toner and a carrier, and develops an electrostatic latent image formed on an image holding body with the first developer to form a toner image; and a developer supply part that stores a second developer containing a second negatively-charged toner having a triboelectric series located on a positive electrode side compared with that of the first negatively-charged toner, and supplies the second developer to the developing part.SELECTED DRAWING: Figure 1 【課題】低密度画像を繰り返し出力したときに生じる、非画像部にトナーが付着する現象（かぶり）の発生を抑制する現像装置を提供すること。【解決手段】第１の負帯電性トナーとキャリアとを含む第１の現像剤を収容し、前記第１の現像剤により、像保持体に形成された静電潜像を現像してトナー像を形成する現像部と、前記第１の負帯電性トナーよりも帯電列が正極側に位置する第２の負帯電性トナーを含む第２の現像剤を収容し、前記第２の現像剤を前記現像部に補給する現像剤補給部と、を備える現像装置である。【選択図】図１
