Abstract: A developing roller includes a roller main body disposed to face, without contact, an outer circumferential surface of an image carrier. A resin coat layer has been formed on an outer circumferential surface of the roller main body, the resin coat layer being made of a resin material having electric conductivity. A product of resistance component Rs [Ω] and electrostatic capacitance component Cs [F] in AC impedance Z of the roller main body is in a range from 2.79×10−7 to 6.77×10−5, the AC impedance Z being obtained when an AC voltage of a predetermined frequency f is applied.

Abstract: A cleaning device includes: a cleaning rotating body 160; a scraping member 130; a toner restriction face 141; and a downstream side restriction portion 140. The cleaning rotating body 160 is arranged in sliding contact with the surface of the image carrying body 2. A front end portion 131 of the scraping member 130 is arranged in contact with or in proximity to a surface of the cleaning rotating body 160. The scraping member 130 is a plate-like member and includes a toner receiving face 133 to which the toner is carried from the front end portion 131. The toner restriction face 141 is arranged to be orthogonal to the toner receiving face 133. The downstream side restriction portion 140 restricts movement of the toner to a downstream side in a rotational direction of the cleaning rotating body 166.
