<p>PROBLEM TO BE SOLVED: To provide an optical writing device of a multiple exposure system which suppresses a density unevenness due to voltage drop on power source wiring, and an image formation device.SOLUTION: A first OLED array and an OLED group of a second OLED array are provided at a same position in a main scan direction, and are adjacent to each other in a sub-scan direction. Any OLED array 201 is connected to power source wiring 421 via an S/H circuit 410 and a drive circuit 430. The OLEDs 201, which are provided at a same position in the main scan direction, receives supply of driving current according to a same brightness signal. The driving current flows to earth wiring 441 via the OLED 201. A constant voltage source, which supplies electric current to the power source wiring 421, are connected to ends of the first OLED array and the second OLED array, which are opposite to each other in the main scan direction of the power source wiring 421.</p> |
