Abstract
An image forming apparatus having a plurality of image bearing members disposed parallel along a conveying direction of recording sheet and a drive power transmission mechanism that translates movement of a drive source to synchronized and uniform movement of the image bearing members is provided. One embodiment of the drive power transmission mechanism includes a plurality of drive power transmission members and a plurality of intermediate transmission members alternately arranged in groups that are offset relative to each other. The drive power and intermediate transmission members in each group are arranged within a predefined angular orientation to ensure synchronized, uniform movement of the image bearing members and uniform distribution of the toner for each color of the color image being recorded.
