摘要： Disclosed is an optical scanning device including a light source including multiple light-emitting elements, the multiple light-emitting elements being arranged in a linear manner, a collimator lens to collimate a light beam from the light source, a light-deflecting device to deflect a light beam having passed through the collimator lens to a medium to be scanned and scan the medium with the light beam, and a rear optical system arranged in an optical path between the collimator lens and the medium to be scanned, wherein the collimator lens deviates an image surface in a direction opposite to an image surface deviation on the medium to be scanned by a nearly same amount as the image surface deviation, the image surface deviation being caused by a change of an image height of the light source, and the change being caused by the rear optical system.

摘要： An optical scanning device is disclosed, including: a light deflection part, an imaging optical element, a variable focus optical element, and a focal point control device. The light deflection part repeatedly deflects and scans a light flux emitted from a light source on a scan surface. The imaging optical element forms an image in a vicinity of the scan surface with the light flux. The focal point control device changes a focal distance of the variable focus optical element, which is arranged in an optical path from the light source to the light deflection part, in executing each of deflection scans, and correct an image misalignment on the scan surface due to an optical path difference for each scan angle.
