Patent number: 10895825Abstract: A developer accommodating container includes a developer accommodating portion, a stirring member, and a drive transmitting member. The developer accommodating container further includes an elastic member fixed to the stirring member at one end portion thereof and capable of expanding and contracting in a direction along a longitudinal direction of the developer accommodating portion. With respect to the longitudinal direction, the stirring member is disposed so as to form (1) a first gap between one end portion thereof and an inner surface of the developer accommodating portion on one side and (2) a second gap between the other end portion thereof and another inner surface of the developer accommodating portion on the other side. The stirring member is supported by the developer accommodating portion so as to be movable in the longitudinal direction relative to the developer accommodating portion.Type: GrantFiled: March 19, 2019Date of Patent: January 19, 2021Assignee: CANON KABUSHIKI KAISHAInventors: Takatoshi Hamada, Naoya Asanuma, Yohei Kusano, Hideki Kakuta

Patent number: 10678164Abstract: A developer container includes a developer accommodating portion, a rotatable member, and a flexible sheet member. The developer container further includes an elastically deformable elastic member. With respect to a longitudinal direction of the developer accommodating portion, between an end portion of the rotatable member and an inside surface of the developer accommodating portion, a gap is formed to permit movement of the rotatable member relative to the developer accommodating portion. In an unused state, the sheet member is elastically deformable together with the elastic member by the movement of the rotatable member relative to the developer accommodating portion in the longitudinal direction.Type: GrantFiled: March 19, 2019Date of Patent: June 9, 2020Assignee: CANON KABUSHIKI KAISHAInventors: Yohei Kusano, Naoya Asanuma, Takatoshi Hamada
