DEVELOPING UNIT WITH DRIVE TRANSMISSION MECHANISM, AND IMAGE FORMING APPARATUS INCLUDING THE SAME

PROBLEM TO BE SOLVED: To provide a developing unit, wherein the drive transmission means of an image forming apparatus body is simplified, the installation number of driving means is reduced, and a maintenance work is easily performed even when a trouble occurs in the drive transmission means, and to provide the image forming apparatus including the developing unit.SOLUTION: The developing unit includes: a first drive connection member for transmitting a driving force to a magnetic roller; a driving force transmission member for transmitting the driving force, which has been transmitted by the first drive connection member, to a stirring part and a developing roller; and a second drive connection member connected to the stirring shaft of the stirring part, and configured to transmit a driving force to convey the toner from the toner supply part of the image forming apparatus body to the toner receiving part. Accordingly, the number of the drive transmission members installed in the image forming apparatus body is reduced.
