Image forming apparatus including an exposure head that exposes a photosensitive member

An image forming apparatus comprising:

• multiple photosensitive members;
• multiple exposure heads configured to respectively expose the photosensitive members, each of the exposure heads including:
• a substrate having an elongated shape extending in axial directions of the photosensitive members;
• multiple light emitting elements mounted on one surface of the substrate, the multiple light emitting elements being arranged in longitudinal directions of the substrate;
• and
• a connector provided on a surface of the substrate opposite the one surface of the substrate on which multiple light emitting elements are mounted,
• a control circuit board;
• multiple flexible flat cables, each of which is configured to electrically connect each connector to the control circuit board;
• and
• multiple exposure support members configured to respectively support the exposure heads in a posture where the light emitting elements are disposed on an upper side and the connector is disposed on a lower side in upward and downward directions of the image forming apparatus,
• wherein each of the flexible flat cables has a contact point electrically connected to each connector of the exposure heads and a reinforcing portion provided on a surface opposite the one where the contact point is disposed, the reinforcing portion having a protruding portion that protrudes from the surface opposite the one where the contact point is disposed, and
• wherein each flexible flat cable is connected to each connector of each exposure head held by each exposure support member in the posture such that each reinforcing portion is disposed on a left side of each contact point in leftward and rightward directions of the image forming apparatus crossing the axial directions.
