摘要： This invention makes it possible to prevent any uneven density and degradation in resolution in reciprocal laser scanning using a movable mirror. An image forming apparatus forms an image on a photosensitive member by scanning the photosensitive member with a laser beam reflected by a movable mirror with reciprocating the movable mirror whose rotation angle is changeable in accordance with an electrical signal. The apparatus detects the rotation direction of the movable mirror, and weights, on the basis of the rotation direction, image data of two lines along the sub-scanning direction in correspondence with the ratio of the scanning length after the start of laser write for a line of laser scanning to compensate the image to be formed using the movable mirror.

摘要： An image-recording apparatus 1 includes image recording assembly 60 and a control section 40 having image-processing section 44 . The image-processing section divides the image data indicative of the complete image into a plurality of image data pieces indicative of divided images, detects two adjoining divided-images that individually have a joint portion and adjoin each other at the respective joint portions, in the divided images indicated by the divided image data pieces and rotates one of the adjoining divided-images so as to make a recording direction of one of the adjoining divided-images opposite to a recording direction of the other adjoining divided-image. The control section controls the image recording assembly so that a recording medium carries in one direction during recording all divided-images. The divided images are recorded on the respective recording-media one by one to form a plurality of output images. The plurality of output images configure one complete image.

摘要： PROBLEM TO BE SOLVED: To provide a light deflector capable of stably maintaining a scan position on a scanned surface and keeping good disposition accuracy of each of multiple movable mirrors so as to form a high-quality image when combining the movable mirrors.
SOLUTION: The movable mirror 441 serves as a deflector which is supported by a torsional beam as a rotary shaft and is constituted so as to deflect an optical beam emitted from a light source and scan an area to be scanned. The movable mirror 441 is controlled by a driving circuit and vibrates in a reciprocating manner by periodical application of a rotational torque. The driving circuit is disposed on a circuit board 453. The movable mirror 441 is integrally supported by the circuit board 453. The direction of a mirror surface of the movable mirror 441 is decided on a contact plane orthogonal to the torsional beam by using a reference hole 455 and a sub-reference hole 456 as positioning reference.
