Abstract
In order to obtain a preferable image without 'stripe-shaped unevenness', an exposure apparatus comprising first and second exposure heads having light emitting sections emitting light with first and second intensity arranged in main and sub scanning directions such that an exposure area including an overlapped exposure area overlapping an exposure area of the first exposure head is exposed by the second exposure head and a driving control unit by which light emitting sections of the first and second exposure heads are lit at a predetermined timing in the overlapped exposure area such that a difference in the maximum exposure amount between pixels adjoining each other in the main scanning direction is smaller than a difference in the maximum exposure amount between each pixel in the exposure area of the first exposure head and each pixel in the exposure area of the second exposure head, is provided.
