    摘要: A cleaning member includes a core and first and second foamed elastic layers wound around an outer peripheral surface of the core in a double-helical pattern. The compressive stress F1 of the first foamed elastic layer is greater than the compressive stress F2 of the second foamed elastic layer. The cleaning member cleans a member to be cleaned with the first and second foamed elastic layers in contact with a surface of the member to be cleaned.

    摘要: A cleaning member includes a core and an elastic layer that is helically wound around an outer peripheral surface of the core. The elastic layer is divided into three or more elastic layer sections in a width direction, and a width of the elastic layer sections at both ends in the width direction is greater than a width of the one or more elastic layer sections in a central region between the elastic layer sections at both ends in the width direction. Alternatively, the elastic layer is divided into three or more elastic layer sections in the width direction, and a minimum thickness of the elastic layer sections at both ends in the width direction is smaller than a minimum thickness of the one or more elastic layer sections in the central region between the elastic layer sections at both ends in the width direction.

    摘要: A cleaning member includes a core and an elastic layer disposed on an outer peripheral surface of the core. A circumferential cover length over which the elastic layer covers the core in a circumferential direction is greater at least at one of first and second end portions in an axial direction of the core than at a central portion in the axial direction. The central portion in the axial direction extends from one end to the other end of the core in the axial direction. When the cleaning member is rotated by a member to be cleaned, a non-contact region in which the first and second end portions in the axial direction are not in contact with the member to be cleaned is in a range from approximately 0° to approximately 15° in terms of a rotation angle of the cleaning member viewed from one side in the axial direction.

    摘要: A charging device includes a charging member that charges a member to be charged and a cleaning member that is disposed in contact with a surface of the charging member and that cleans the surface of the charging member. The cleaning member includes a core and two foamed elastic layers disposed adjacent to each other in an axial direction around an outer peripheral surface of the core from one end to another end of the core in a substantially double-helical pattern. The two foamed elastic layers are a first foamed elastic layer having an average skeleton size D1 smaller than an average spacing Sm between irregularities in the surface of the charging member and a second foamed elastic layer having an average skeleton size D2 larger than or equal to the average spacing Sm between the irregularities in the surface of the charging member.

    摘要: A cleaning body includes a shaft and an elastic layer that is helically wound around the shaft from one end side to the other end side of the shaft and fixed on the shaft and that cleans a body to be cleaned while the elastic layer rotates. The elastic layer includes a division portion having plural divided segments and having a length of from 20% to 70% of the full length of the elastic layer. The division portion is located in a longitudinal central portion of the elastic layer. In the sectional view perpendicular to the axial direction of the shaft, a minimum thickness part in the longitudinal central portion of the elastic layer is from 5% to 12% thicker than a minimum thickness part in each longitudinal end portion of the elastic layer.

    摘要: A cleaning member includes a core and an elastic layer helically wound around an outer peripheral surface of the core so as to extend from one end to the other end of the core. When the cleaning member is rotated by a member to be cleaned, a non-contact region in which a first end portion and a second end portion of the elastic layer in an axial direction of the core are not in contact with the member to be cleaned is in a range from approximately 0° to approximately 60° in terms of a rotation angle of the cleaning member viewed from one side in the axial direction of the core.
