摘要： In an image forming apparatus of the present invention, a plurality of writing electrodes 3b are supported by an elastic and flexible substrate 3a such that the writing electrodes are aligned in a plurality of rows each extending in the axial direction of the latent image carrier (in the main scanning direction). The writing electrodes 3b are each formed in, for example, a triangle and are arranged in such a manner that the orientations of the triangles of the writing electrodes are alternately inverted. In this case, one end of the triangle base of a writing electrode is overlapped with one end of the triangle base of a next writing electrode 3b, as seen in the direction perpendicular to the axial direction of the latent image carrier 2 (the rotational direction of the latent image carrier 2; the feeding direction). Therefore, this design prevents occurrence of image defect due to linear stains and allows foreign matters adhering to the surface of the latent image carrier 2 to pass through spaces between the adjacent writing electrodes 3b.

摘要： In a color image forming apparatus, a looped belt member is stretched and circulated by at least a drive roller and a driven roller so as to have a tensed side and a slack side. Each of plural image supporting members supports a single color toner image thereon, and abuts onto the slack side of the belt member to define a transferring position at which the toner image is transferred onto either the belt member or a recording medium held by the belt member, while being rotated. A circumferential velocity of each image supporting member is determined so as to be higher than a circulation velocity of the belt member.

摘要： An optical scanning device 65 is adapted to bring a deflector mirror plane 651 into independent pivotal motions about a first axis and a second axis perpendicular to each other. A mirror driver section including a first axis driver and a second axis driver is so controlled as to bring the deflector mirror plane 651 into pivotal motion about the first axis thereby deflecting a light beam L for scanning along a main scan direction. On the other hand, the deflector mirror plane 651 is pivotally moved about the second axis thereby to adjust the scanned beam L for its position on a photosensitive member 2 with respect to a subscan direction. Thus, even if the scanned beam is deviated from a reference scan position with respect to the subscan direction due to component tolerances or assembly errors, such a deviation can be corrected.
摘要翻译：光学扫描装置65适于使偏转镜面651围绕彼此垂直的第一轴线和第二轴线相互独立的枢转运动。控制包括第一轴驱动器和第二轴驱动器的镜驱动器部分，以使偏转镜面651围绕第一轴线枢转运动，从而沿着主扫描方向偏转用于扫描的光束L. 另一方面，偏转器镜面651围绕第二轴线枢转运动，从而相对于副扫描方向调整扫描光束L在感光元件2上的位置。因此，即使由于部件公差或组装误差而使扫描光束相对于副扫描方向偏离参考扫描位置，也可以校正这种偏差。
