Developing device conveying assembly for image forming apparatus and image forming apparatus having the same

An image forming apparatus comprising:

• a body;
• a photoconductor which is disposed inside the body and has an electrostatic latent image formed thereon;
• and
• a developing device to provide the photoconductor with a developing agent, the developing device comprising:
• a developing agent accommodating compartment;
• at least one rotation member disposed in the developing agent accommodating compartment;
• a plurality of developing agent convey members which convey the developing agent existing in the developing agent accommodating compartment while rotating around the at least one rotation member;
• and
• a plurality of torque limiters which are disposed between the at least one rotation member and the plurality of developing agent convey members and that are coupled to the at least one rotation member and the plurality of developing agent convey members such that at least one of the plurality of developing agent convey members performs a relative motion with respect to remaining developing agent convey members of the plurality of developing agent convey members.

A developing agent convey apparatus of an image forming apparatus, comprising:

• a first rotation member and a second rotation member disposed in a developing agent accommodating compartment and that are spaced apart from one another by a predetermined interval;
• a plurality of developing agent convey members to convey developing agent stored the developing agent accommodating compartment while rotating around the first rotation member and the second rotation member;
• and
• a torque limiter that is coupled to the first rotation member and the plurality of developing agent convey members, the torque limiter being disposed between first rotation member and the plurality of developing agent convey members.
