Publication number: 20240103423Abstract: A cleaning member includes: an elastic contact plate that includes a distal end surface with a corner portion to be brought into contact with a cleaning target surface, which is moved with toner attached thereto, of a cleaning target body; and a support plate bonded to the elastic contact plate from a back surface side of the elastic contact plate to support the elastic contact plate, the support plate being more rigid than the elastic contact plate. The distal end surface of the elastic contact plate projects from a distal end surface of the support plate.Type: ApplicationFiled: March 3, 2023Publication date: March 28, 2024Applicant: FUJIFILM Business Innovation Corp.Inventors: Tatsuya TAKAHASHI, Naoya MITAMURA, Akira SHIMODAIRA

Patent number: 10908553Abstract: A cleaning device includes a cleaning unit that cleans an object to be cleaned that moves by bringing a contact portion into contact with the object to be cleaned, the contact portion extending in a width direction that crosses a moving direction in which the object to be cleaned moves, the cleaning unit including a supported surface at a downstream side in the moving direction; and a support unit including a supporting surface that faces the supported surface and that includes a bonded portion bonded to the supported surface, the support unit supporting the cleaning unit at the bonded portion. The bonded portion is provided at an intermediate position of the supporting surface in a direction in which the supporting surface extends toward the object to be cleaned, and the support unit includes an extending portion that extends further toward the object to be cleaned from the bonded portion.Type: GrantFiled: January 15, 2020Date of Patent: February 2, 2021Assignee: FUJI XEROX CO.. LTD.Inventors: Kanji Watanabe, Naoya Mitamura
