Abstract
An electrophotographic color image forming apparatus is provided having a plurality of developing units that respectively include developer rollers to develop an electrostatic latent image formed on a photoconductor by applying toner to the electrostatic latent image. A plurality of toner cartridges respectively include agitators and are arranged in a lengthwise direction of the developer roller to supply toner to the developing units. A plurality of shafts are connected to each other through a universal joint to transmit rotational motion of a driving motor to the agitators.
