Developing Cartridge |
摘要 |
A developing cartridge includes: a developing roller that is rotatable about a developing roller axis line, which extends in a predetermined direction; a supply roller, which is rotatable about a supply roller axis line, which extends in the predetermined direction, and which supplies developer to the developing roller; a developing roller driving gear that is connected to the developing roller; a supply roller driving gear that is connected to the supply roller; and a driving force transmission gear, which is rotatable about a gear axis line extending in the predetermined direction, and which includes: a first gear part meshed with the developing roller driving gear; and a second gear part meshed with the supply roller driving gear. The driving force transmission gear transmits driving force to the developing roller driving gear and the supply roller driving gear. |

1. A developing cartridge comprising:
a developing roller configured to rotate about a developing roller axis; a supply roller configured to rotate about a supply roller axis extending parallel to the developing roller axis, wherein the supply roller is configured to supply developer to the developing roller; a developing gear connected to and rotatable with the developing roller; a supply gear connected to and rotatable with the supply roller; and an input gear including:
a coupling member configured to receive driving force;a first gear being meshed with the developing gear, wherein the first gear has a first helical tooth pattern on a circumferential surface thereof, the first helical tooth pattern having tooth traces following first helix pitches, anda second gear being meshed with the supply gear, wherein the second gear has a second helical tooth pattern on a circumferential surface thereof, the second helical tooth pattern having tooth traces following second helix pitches in a direction opposite to a direction of the first helix pitches. |
