Patent abstract

An electrode of an image bearing unit and an electrode of a power supply are positioned in the front, rather than far inside of the main body of the image forming apparatus. A holder opposes these electrodes in an openable/closable manner. The holder includes an electric conductor that electrically connects the electrode of an image bearing unit and an electrode of a power supply when the holder is closed. The image bearing unit can be detached or attached when the holder is open.
