摘要: It is aimed to provide a developer cartridge provided with a detection gear having a novel structure. A first gear (transmission gear 400) includes a small-diameter gear portion 450 and a large-diameter gear portion 440 having a diameter larger than a diameter of the small-diameter gear portion 450. The second gear (detection gear 300) includes: a first columnar portion centered on a second axis CL2; a second columnar portion having a smaller diameter smaller than the first columnar portion; a first engagement portion (first gear portion 332) extending along a portion of a peripheral surface of the first columnar portion and engageable with the small-diameter gear portion 450; a second engagement portion (second gear portion 352) extending along a portion of a peripheral surface of the second columnar portion and positioned closer to a housing than the first engagement portion to the housing in an axial direction and engageable with the large-diameter gear portion 440; and a protrusion (detection protrusion 301) protruding in the axial direction and rotatable together with the first engagement portion and the second engagement portion. The second engagement portion is engageable with the large-diameter gear portion 440 after the first engagement portion is engaged with the small-diameter gear portion 450.

摘要: A developing cartridge includes first and second rotary members. The first rotary member is rotatable from a first position to a second position and from the second position to a third position, and includes a first gear part and a first rib. The first rib extends along an addendum circle of the first gear part. The second rotary member includes a second gear part and a second rib protruding outward in a radial direction of the second rotary member. The second rib is in contact the first rib during rotation of the first rotary member from the first position toward the second position. The second rib is separated from the first rib during rotation of the first rotary member from the second position toward the third position.

摘要: A developing device 10 includes an auger or an agitator that is capable of supplying toner in a toner accommodation chamber to a developing chamber and is rotatable about an auger axis extending in an axial direction, a transporting gear 26 that is rotatable together with the auger or the agitator, and a moving gear 33 that is in mesh with a coupling gear 22B and is rotatable both counterclockwise and clockwise. The moving gear 33 is movable while being in mesh with the coupling gear 22B between a first position where the moving gear 33 is in mesh with the transporting gear 26 and a second position where the moving gear 33 is out of mesh with the transporting gear 26. The moving gear 33 moves to the first position when the coupling gear 22B rotates counterclockwise and to the second position when the coupling gear 22B rotates clockwise.

摘要: A developing cartridge includes: a housing (11, 211); a developing roller (12) rotatable about a first axis (12X) extending in an axial direction; a first helical gear (22, 26) and a second helical gear (24, 225) positioned at an outer surface (11C, 211C) of the housing; and an engaging member (50, 250A) movable together with the second helical gear. The second helical gear meshes with the first helical gear and is rotatable in a first rotational direction and a second rotational direction. The second helical gear is movable in the axial direction between a first position and a second position closer to the outer surface than the first position. The second helical gear rotates in the first rotational direction to move toward the first position. The second helical gear rotates in the second rotational direction to move toward the second position whereby the engaging member engages a part of the outer surface to terminate rotation of the second helical gear.

摘要: A developing cartridge includes: a housing; a developing roller rotatable about an axis extending in an axial direction; a first helical gear and a second helical gear positioned at an outer surface of the housing; a cover covering part of the second helical gear; and an engaging member movable with the second helical gear. The second helical gear meshes with the first helical gear and is rotatable in first and second rotational directions. The second helical gear is movable in the axial direction between a first position and a second position farther away from the outer surface than the first position. The second helical gear rotates in the first rotational direction to move to the first position. The second helical gear rotates in the second rotational direction to move to the second position whereby the engaging member engages part of the cover to terminate rotation of the second helical gear.
