Patent number: 11119425Abstract: If a user is not familiar with the operation for the developer supply container, the rotating operation for the developer supply container may be insufficient, so that developer supply container does not reach a predetermined operating position, with the result of abnormal developer supply. by increasing a rotation load of a second gear 6 which is in an operable connection with a drive gear member 12 of the developer receiving apparatus 10 by a function of a locking member 7, the developer supply container 1 mounted to the developer receiving apparatus 10 is rotated toward the supply position. After the developer supply container 1 rotates to the supply position, the locking by the locking member 7 is released, by which the rotation load applied to the second gear 6 is reduced, so that drive transmission, thereafter, to the feeding member 4 for developer supply is smooth.Type: GrantFiled: January 10, 2020Date of Patent: September 14, 2021Assignee: CANON KABUSHIKI KAISHAInventors: Nobuo Nakajima, Ayatomo Okino, Katsuya Murakami, Toshiaki Nagashima, Yutaka Ban
