    摘要: An image forming apparatus includes a potential applier, a cleaning device and a hardware processor. The cleaning device includes an abutting member abutting a surface of the image carrier and removes residual toner on the surface of the image carrier by means of the abutting member after a toner image formed on the surface of the image carrier is transferred to a transfer material. In a cleaning mode for removing a foreign matter attached to the abutting member of the cleaning device, the hardware processor controls the potential applier to alternately apply a first potential and a second potential which is lower than the first potential to the image carrier so as to periodically change a potential of the abutting member without causing saturation.

    摘要: An image forming apparatus includes an electrophotographic photoreceptor, a charging device, an electrostatic latent image forming device, a developing device, a transfer device, and a cleaning device, and further includes an intercepting device that includes an intercepting member separated from the electrophotographic photoreceptor by a gap so that a distance from the surface of the electrophotographic photoreceptor to the intercepting member is about 0.3 to 0.9 (inclusive) times a volume-average particle size of toner particles. The intercepting member is used to intercept residual toner particles at a position downstream of the transfer device and upstream of the cleaning device in a rotation direction of the electrophotographic photoreceptor, the residual toner particles remaining on the surface of the electrophotographic photoreceptor.

    摘要: An image formation apparatus includes: an image carrier; a developing device which develops an electrostatic latent image formed on the image carrier as a toner image; a transfer device which transfers the toner image to a medium; a cleaning device which recovers toner remaining on the image carrier after the toner image is transferred; and a lubricant application adjustment mechanism which applies a lubricant on the image carrier and recovers toner present on the image carrier upstream of the cleaning device; and a controller which controls the lubricant application adjustment mechanism. The controller causes the lubricant application adjustment mechanism to recover more toner when the toner image formed on the image carrier has a larger image area ratio.

    摘要: A cleaning device comprises: a to-be-cleaned member; a cleaning member that cleans the surface of the to-be-cleaned member; a conveying member that conveys a substance removed from the surface of the to-be-cleaned member to outside of the device; a rotatable collecting member that conveys with its surface the substance toward the conveying member; and a partitioning member that guides the substance from the collecting member to the conveying member. The collecting member comprises a conveying portion that carries and conveys the substance; and a protrusion that protrudes toward an upstream side of the conveying portion in a rotating direction of the collecting member. One end of the partitioning member faces the rotating collecting member, and the other end faces the conveying member. The conveying portion and the protrusion are brought into contact with the partitioning member by the rotation of the collecting member.

    摘要: An image-forming apparatus include an image bearer; a cleaning device to clean a surface of the image bearer; an air-blowing device to blow outside air; a temperature/humidity detector to detect temperature and humidity outside of the image-forming apparatus; and a controller to determine absolute humidity from detected temperature and humidity. Based on the absolute humidity, a waiting time from a time when a previous image-forming operation ends until the air-blowing device stops, in a stand-by state of an image-forming operation, and an unused time from a time when the air-blowing device stops until the air-blowing device resumes, the controller determines whether or not a polishing operation of the image bearer by the cleaning device after the air-blowing device is unused is executed in starting the operation of the blowing device.

    摘要: A light scanning device includes a housing, a plurality of permeable members, a plurality of cleaning members, a plurality of cleaning holders, a linear member, and a driving unit. The plurality of permeable members close the respective plurality of the emission ports. The plurality of cleaning holders extend over the plurality of the permeable members adjacent to one another. The plurality of the cleaning holders each have a holding unit that holds at least the two cleaning members. The linear member is connected to the plurality of the cleaning holders. The driving unit causes the linear member to run circularly. The cleaning members each slide on the corresponding permeable member in association with the linear member running circularly. The cleaning holders each connected to the linear member at a center of the holding unit in an extending direction of the holding unit.
