LED printer and drive method having an energy distribution flattening function

摘要

A printer including a light emitting body for emitting light along a main scanning direction. A photosensitive surface of a photosensitive body is sensitized by the light emitted from the light emitting body. The photosensitive surface is moved relative to the light emitting body at a predetermined distance along a sub scanning direction perpendicular to the main scanning direction. While the photosensitive surface is moved at the predetermined distance along the sub scanning direction, the light emitting body emits the lights at a predetermined period. The predetermined period is determined to be a time required for moving the photosensitive surface at a dimension of the light emitting body along the sub scanning direction.
