Abstract
An image forming apparatus includes an intermediate transfer member bearing a toner image and image forming units arranged side by side, with each image forming unit having a developing device forming the toner image, a magnetic permeability sensor detecting a toner density of a developer in the developing device, and a cleaning unit having a cleaning member which removes toner remaining on an image bearing member and a conductive support member which supports the cleaning member. The apparatus further includes a conductive member facing the magnetic permeability sensor of the most upstream image forming unit and arranged upstream of that image forming unit. The developing device of one of adjacent image forming units is opposed to the cleaning unit of another unit which is arranged downstream and is next to the developing device of the one of the adjacent image forming units.
