Patent number: 9046872Abstract: A cooling device includes a cooling member to cool a recording material. The cooling member includes a cooling surface member, a heat exchanging member, and a fastening member. The cooling surface member has a cooling surface to directly or indirectly contact the recording material and absorb heat of the recording material to cool the recording material. The heat exchanging member is directly or indirectly joined to the cooling surface member to radiate heat absorbed by the cooling surface member directly or indirectly via a radiation member. The fastening member fastens the cooling surface member and the heat exchanging member to retain a joined state in which the cooling surface member and the heat exchanging member are directly or indirectly joined to each other. The cooling surface member and the heat exchanging member are separable from the joined state to a separated state without damaging the fastening member.Type: GrantFiled: February 18, 2014Date of Patent: June 2, 2015Assignee: Ricoh Company, Ltd.Inventors: Keisuke Ikeda, Makoto Nakura, Susumu Tateyama, Hiroaki Miyagawa, Yasuaki Toda, Yutaka Shoji, Kenji Ishii, Kenichi Takehara, Hiromitsu Fujiya, Keisuke Yuasa, Shinji Kato, Tomoyasu Hirasawa
