To suppress cleaning failure of an image holding body while reducing the use amount of toner as compared with a configuration in which a toner different from the toner removed from the surface of the image holding body is supplied as the lubricant to a contact part of a cleaning member for the surface.SOLUTION: A cleaning device includes: a cleaning member for removing toner from the surface of an image carrier by bringing the upper end into contact with the surface of the image carrier from the downstream side in a rotation direction of the image carrier, a housing which supports the cleaning member and stores the toner removed from the surface of the image holder by the cleaning member; and a conveyance member which is provided inside the housing and conveys the toner stored inside the housing to the outside of the housing at the same height as a contact part of the cleaning member for the surface of the image carrier or above the contact part.SELECTED DRAWING: Figure 3 【課題】像保持体の表面に対する清掃部材の接触部に、当該表面から除去したトナーとは別のトナーを潤滑材として供給する構成と比較して、トナーの使用量を低減しつつ、像保持体の清掃不良を抑制することである。【解決手段】清掃装置は、像保持体の表面に前記像保持体の回転方向の下流側から上端部を接触させ、前記表面からトナーを除去する清掃部材と、前記清掃部材を支持するとともに、前記清掃部材によって前記像保持体の前記表面から除去されたトナーを貯留する筐体と、前記筐体の内部に設けられ、前記像保持体の前記表面に対する前記清掃部材の接触部と同じ高さ又は前記接触部よりも上側で、前記筐体の内部に貯留されたトナーを前記筐体の外部へ搬送する搬送部材と、を備える。【選択図】図３
