ABSTRACT:
Providing an exposure unit using an organic electroluminescence element with a large emitted light quantity.The organic electroluminescence element has, on a substrate31, an anode32acting as a hole injection electrode, a cathode33acting as an electron injection electrode, a first and second emission layers34and35each having a light emission region, and a charge generation layer38injecting electrons into the light emission layer34lying close to the anode32and injecting holes into the light emission layer35lying close to the cathode33, these layers being arranged between the anode32and the cathode33.
