摘要： A developing device may include 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 that is rotatable together with the auger or the agitator, and a moving gear that is in mesh with a coupling gear and is rotatable both counterclockwise and clockwise. The moving gear is movable while being in mesh with the coupling gear between a first position where the moving gear is in mesh with the transporting gear and a second position where the moving gear is out of mesh with the transporting gear. The moving gear moves to the first position when the coupling gear rotates counterclockwise and to the second position when the coupling gear rotates clockwise.

摘要： A developing cartridge includes: a first frame; and a second frame melt-bonded to the first frame. The first frame includes: a first melt-bonding surface; and a second melt-bonding surface closer to a developing roller than the first melt-bonding surface. The second frame includes: a third melt-bonding surface; a fourth melt-bonding surface; and a center surface facing the first frame. The center surface is closer to an axial center region of the developing roller than the fourth melt-bonding surface in the axial direction. The center surface has a first center surface and a second center surface closer to the developing roller than the first center surface in the first direction. The second center surface forms an obtuse angle with the first center surface and is separated from the first frame farther than the fourth melt-bonding surface in a direction perpendicular to the fourth melt-bonding surface.

摘要： A developing cartridge is provided for use with an image forming apparatus and may include a housing, a developing roller rotatably provided in the housing, and a developing roller gear configured to rotate integrally with the developing roller. Further, the developing cartridge can include a driving input gear configured to receive an external driving force and apply the received driving force to the developing roller gear. The driving input gear can be meshed with the developing roller gear or an intermediate gear can be provided to mesh with the developing roller gear and the driving input gear. Such an intermediate gear can be configured to apply the received driving force to the developing roller gear. Also, the developing cartridge can include a receiving member which is disposed between the housing and the developing roller gear and between the housing and the driving input gear.
