Patent number: 10054900Abstract: A developer cartridge includes a first gear rotatable about a first axis extending in an axial direction, and a second gear rotatable in a rotation direction about a second axis extending in the axial direction. The second gear includes: an engagement portion engageable with gear teeth of the first gear; a first protrusion and a second protrusion protruding in the axial direction. The first and second protrusions extend to be spaced apart from each other in the rotation direction. The first protrusion has first end and a second end defining a first angle therebetween about the second axis. The second protrusion has a third end and a fourth end farther away from the first protrusion than the third end is in the rotation direction. The second end and the third end define a second angle therebetween about the second axis. The first angle is smaller than the second angle.Type: GrantFiled: February 9, 2017Date of Patent: August 21, 2018Assignee: Brother Kogyo Kabushiki KaishaInventor: Takuro Kusama
