Abstract
An exposure apparatus comprises an exposure head, a memory and at least one processor. The exposure head includes light-emitting elements, and a rod lens array. A photosensitive body is rotationally driven. The light-emitting elements are arranged in a direction intersecting a direction of rotation of the photosensitive body. The rod lens array forms an image of light on the photosensitive body. The light is outputted from any of the light-emitting elements based on image data, passes through the rod lens array and reaches the photosensitive body. The memory stores correction data for correcting a streak image. The at least one processor corrects the image data based on the correction data read out from the memory.
