摘要： A cleaning device includes a first cleaning member, a first opposing member, a second cleaning member, a second opposing member, and a pressing member. The first and second cleaning members clean an outer surface of a belt member by coming into contact with the outer surface. The first and second opposing members are in contact with an inner face of the belt member at positions that are opposite the first and second cleaning members. The pressing member is disposed between the first and second opposing members and is in contact with the outer surface of the belt member. The pressing member presses a portion of the belt member that is located between the first and second opposing members from an outer surface side of the belt member toward an inner face side of the belt member.

摘要： Terminals of upstream and downstream sides of an in-service line and a detour line are connected by optical couplers. An optical oscilloscope is connected to one optical coupler, and a chirped pulse light source is connected to the other optical coupler to thereby form dualized lines. The detour line includes an optical line length adjuster for compensating for the phase difference of optical transmission signals that occurs because of the optical line length difference with the in-service line. Pulse light in which an optical frequency is chirped is transmitted from the chirped pulse light source. The pulse light is branched by the second optical coupler, passes through the in-service line and the detour line, is multiplexed again by the first optical coupler, and is measured by the optical oscilloscope. While matching an arrival time of the pulse light, the optical line length is adjusted by the optical line length adjuster so as to minimize the size of upper and lower limits of an interference waveform generated in an upper part of the pulse light waveform or so as to make a frequency of an interference waveform become zero.

摘要： A charging device includes a charger facing a rotatably supported image carrier and configured to charge the image carrier on which an electrostatic latent image is to be formed, and a movement mechanism configured to move the charger between a charging position at which the charger is close to the image carrier and a retracted position at which the charger is retracted away from the image carrier. The movement mechanism includes a support member supporting the charger that has been moved to the retracted position by the movement mechanism, and a movable member configured to move when a driving force from a drive source is transmitted thereto. The movable member moves to the charging position or the retracted position when the movable member is moved in a direction of a rotational axis of the image carrier while being in contact with the support member.

摘要： An image forming apparatus includes a latent-image forming member including a latent-image carrier and support portions, a charging member including a discharge electrode and a control electrode, restraining portions that restrain both ends of the control electrode in a width direction, and abutting portions that are provided on the support portions, that include curved surfaces, and that are abutted against the control electrode. The curved surfaces have a center of curvature that coincides with a rotational center of the latent-image carrier, and are at a position where a distance from the latent-image carrier in a radial direction is equal to a distance between the latent-image carrier and the control electrode. When the charging member is attached to the latent-image forming member, the control electrode is abutted against the curved surfaces by the restraining portions and is deformed along the curved surfaces.
