  • Patent number: 10788768
    Abstract: A charging device includes a charging member and a cleaning member. The charging member electrically charges a surface of a charging target member and is rotatable while being in contact with the surface of the charging target member. The cleaning member is in contact with a surface of the charging member and removes a foreign object attached to the surface of the charging member. Surface free energy of the surface of the charging member is 5.00 dynes per centimeter or more. A dynamic friction coefficient of the surface of the charging member and a surface of the cleaning member falls within a range from 0.48 to 0.88 both inclusive. The surface free energy and the dynamic friction coefficient satisfy a relation represented by the following expression (1). E??63?+69??(1) “E” is the surface free energy in dynes per centimeter, and “?” is the dynamic friction coefficient.

  • Patent number: 10466614
    Abstract: A developing device includes a hardware processor that performs control not to cause an image to be formed on an image bearing member by a first developer bearing member and to cause a first image to be formed on the image beating member by a second developer bearing member, in which the hardware processor corrects developing conditions of the plural developer bearing members based on a developability detection result of the first image formed by the second developer bearing member.

  • Patent number: 10375254
    Abstract: An image forming apparatus includes a plurality of image formers each capable of forming, on a sheet, an overlap image and a non-overlap image, a fixer that fixes, on the sheet, a whole image composed of the overlap images and the non-overlap images, and a hardware processor that controls each of the plurality of image formers such that a difference in image at a boundary between the overlap image and the non-overlap image is reduced in the whole image.

  • Publication number: 20170184992
    Abstract: An image forming apparatus includes an electrostatic latent image carrier that carries an electrostatic latent image, a charging member that charges the electrostatic latent image carrier by contacting with the electrostatic latent image carrier, the charging member being rotatable around an axis, and a development part that develops the electrostatic latent image by having a developer adhere to the electrostatic latent image. The charging member comprises an axial body that rotates around the axis, a conductive base layer provided around the axial body, and a surface layer provided on an outer circumferential face of the conductive base layer, and surface projections are formed on the surface layer, of which a projection height distribution includes at least two peaks.

  • Patent number: 8269812
    Abstract: The image forming apparatus includes: an image carrier; an exposure head provided along a longitudinal direction of the image carrier, and exposing the image carrier; a housing holding the exposure head; an opening portion formed in the housing, and opening toward a position through which the image carrier and the exposure head face each other; a receiving portion provided in the housing; and a cleaning member having one and different ends, and including: a cleaning portion provided on a one end side where the one end is located, and cleaning a light-emitting face of the exposure head by moving while keeping in contact with the light-emitting face; and a guiding portion coming in contact with the receiving portion and guiding the cleaning portion toward a space between the image carrier and the exposure head when the cleaning portion is inserted into an interior of the housing through the opening portion.
