    Abstract: An image forming apparatus includes a photosensitive member, a charging member, an exposing device, a developing device, a transfer member, a brush, a voltage applying portion, and a control portion controlling a surface potential of the photosensitive member at the brush contacting position. When a value of subtracting a value of the surface potential of the photosensitive member in the brush contacting position from a value of the brush voltage is defined as a contacting position potential difference, the control portion controls the surface potential of the photosensitive member in the brush contacting position so that the contacting position potential difference is changed from a first potential difference to a second potential difference in a predetermined direction which is either one of an increasing direction or a decreasing direction, and then the contacting position potential difference is changed from the second potential difference to a third potential difference in the predetermined direction.

    Abstract: A developing device includes a developing roller, a toner supplying roller, a regulation blade, a casing, a toner receiver support member, a toner receiver member, and a vibration generator. The toner receiver member is disposed along a longitudinal direction of the toner receiver support member facing the developing roller, and has a toner receiving surface inclined downward from the image-carrier side toward the toner-supplying-roller side. The toner receiving surface is disposed to be inclined so as to rise from the toner-supplying-roller side toward the image-carrier side. The toner receiving surface has a plurality of grooves formed therein to be inclined to approach a center part of the toner receiving surface from each end side of the toner receiving surface in its longitudinal direction, from an edge of the toner receiving surface on the image-carrier side toward an edge of the toner receiving surface on the toner-supplying-roller side.

    Abstract: In an image forming apparatus, a coating layer of each of a photoconductor drum and a collecting roller has been formed by a dipping method in which a base body of each of the photoconductor drum and the collecting roller is dipped in a liquid in a state where the base body is in a vertical attitude such that a first end of the base body faces down and a second end of the base body faces up. The collecting roller is supported in a state where the first end of the collecting roller base body and the second end of the drum base body face a same direction.
