Patent Number: 6,798,440

Title: Image recording apparatus

Abstract: An image recording apparatus has light emitting elements arranged in a main scanning direction and an imaging optical system which images light from the light emitting elements on a recording medium. An image is recorded on the recording medium by imaging light from the light emitting elements through the imaging optical system while moving the recording medium in a sub-scanning direction. The imaging optical system is formed of a first optical system consisting of biaxial optical elements, each having a refractive index profile in the main scanning direction and a refractive index in the sub-scanning direction, arranged in the main scanning direction, and a second optical system consisting of an optical element disposed on the light incident side of the first optical system and having a refractive power to light components propagated in the sub-scanning direction but no refractive power to light components propagated in the main scanning direction.
