Toner cartridge with waste toner dispersing member connected to and driven by toner transport member

A toner cartridge comprising:

• a toner container to contain toner, the toner container including a toner outlet;
• a toner transport member comprising a rotation shaft extending in a first direction and arranged in the toner container to transport the toner to the toner outlet by rotating with respect to the rotation shaft in the first direction;
• a waste toner container including a waste toner inlet to receive waste toner, the waste toner inlet arranged in a side portion of the toner container in the first direction;
• a dispersing member arranged inside the waste toner container to transport the waste toner in a second direction to disperse the waste toner inside the waste toner container, wherein the dispersing member may extend in the second direction and may include a body extending in the second direction to stir the waste toner in the second direction;
• a driving transfer member to receive rotation power from the toner transport member to transfer into the movement of the dispersing member in the second direction that is orthogonal to the first direction, wherein the driving transfer member may reciprocate the dispersing member in the second direction to enable the dispersing member to move back and forth along a length of the waste toner container;
• a vibration driving unit comprising:
• a slope portion, extending in the first direction and including a slope in the second direction, provided in either of the dispersing member and the waste toner container;
• a contact portion provided to contact the slope portion in the other of the dispersing member and the waste toner container;
• and
• an elastic member to apply an elastic force to the dispersing member such that the slope portion and the contact portion contact each other,
• wherein the vibration driving unit may vibrate the dispersing member in the first direction in conjunction with reciprocation of the dispersing member in the second direction.

A toner cartridge comprising:

• a toner container to contain toner, the toner container including a toner outlet;
• a toner transport member comprising a rotation shaft extending in a first direction and arranged in the toner container to transport the toner to the toner outlet by rotating with respect to the rotation shaft in the first direction;
• a waste toner container including a waste toner inlet to receive waste toner, the waste toner inlet arranged in a side portion of the toner container in the first direction;
• a dispersing member arranged inside the waste toner container, wherein the dispersing member comprises a rotation shaft extending in a second direction that is orthogonal to the first direction and a spiral wing formed on the rotation shaft to transport the waste toner in the second direction to disperse the waste toner inside the waste toner container;
• and
• a driving transfer member to receive rotation power from the toner transport member,
• wherein the driving transfer member is to convert rotation power of the toner transport member with respect to an axis in the first direction into rotation power with respect to an axis in the second direction and transfers the rotation power to the dispersing member.

An image forming apparatus comprising:

• a main body including a developing device to supply toner to an electrostatic latent image formed on a photoconductor and to develop the electrostatic latent image;
• and
• a toner cartridge to contain toner to be supplied to the developing device,
• wherein the toner cartridge comprises:
• a toner container to contain the toner, the toner container including a toner outlet;
• a toner transport member comprising a rotation shaft extending in the first direction and arranged in the toner container to transport the toner to the toner outlet by rotating with respect to the rotation shaft in the first direction;
• a waste toner container including a waste toner inlet to receive waste toner, the waste toner inlet arranged in a side portion of the toner container in the first direction;
• a dispersing member arranged inside the waste toner container to transport the waste toner in a second direction to disperse the waste toner inside the waste toner container, wherein the dispersing member may extend in the second direction and may include a body extending in the second direction to stir the waste toner in the second direction;
• and
• a driving transfer member to receive rotation power from the toner transport member to transfer into the movement of the dispersing member in the second direction that is orthogonal to the first direction, wherein the driving transfer member may reciprocate the dispersing member in the second direction to enable the dispersing member to move back and forth along a length of the waste toner container,
• wherein the dispersing member comprises a sliding groove extending in a third direction that is orthogonal to the first direction and the second direction, and
• wherein the driving transfer member comprises:
• a rotating member to rotate with respect to a rotation shaft in the first direction, the rotating member including an eccentric pin positioned to deviate from the rotation shaft and inserted into the sliding groove;
• and
• at least one gear to connect the rotating member to the toner transport member.
