摘要： A multibeam scanner for scanning an image area with a plurality of laser beams, comprising a plurality of beam emitting points that emit a plurality of laser beams reaching the image area with respective time lags therebetween, a time lag determination unit that determines at least one of the time lags during a predetermined calculation time, a scan controller that controls the plurality of beam emitting points to emit the plurality of laser beams successively in the image area with the at least one of the time lags determined by the time lag determination unit. The multibeam scanner of the invention, comprises a photodetector that detects any one of the laser beams at a predetermined beam detection position. The time lag determination unit determines the time lag between the nth laser beam and the n+1th laser beam. Therefore, to scan the image area, the photodetector detects the first laser beam at the predetermined beam detection position, prior to the image area, and determines a scan start time for the first laser beam. Then, the scan controller starts controlling the first beam emitting point at the determined scan start time to emit the first laser beam in the image area. The scan controller further controls the n+1th beam emitting point to emit the nth laser beam in the image area with the calculated time lag between the nth laser beam and the n+1th laser beam.

摘要： A multibeam scanner capable of scanning an image forming area with constant beam amounts of laser beams. The multibeam scanner of the invention performs automatic power control (APC) on each of a plurality of beam emitting points one by one during corresponding time durations, respectively, in a non-image forming area. The laser beam emitted last among the plurality of laser beams is controlled to reach a predetermined beam detecting position within the corresponding time duration. Before scanning the image forming area, the multibeam scanner determines a scan start timing upon the detection of the laser beam emitted at the beam detecting position, which has been stabilized during APC. This arrangement allows the laser diode to avoid wasting time again and again, as rise time for stabilizing the laser beam for performing APC and for identifying the scan start timing, and to secure the time durations as long as possible. It is therefore possible to perform APC against the laser diodes properly during the sufficient time durations and, at the same time, possible to determine the scan start timing precisely by detecting the stabilized laser beam.
摘要翻译：一种能够以恒定光束量的激光束扫描图像形成区域的多光束扫描仪。本发明的多光束扫描器分别在非图像形成区域中的相应时间期间逐个地在多个光束发射点的每一个上执行自动功率控制（APC）。控制在多个激光束中最后发射的激光束在相应的持续时间内到达预定的光束检测位置。在扫描图像形成区域之前，多光束扫描器在检测到在APC期间已经稳定的光束检测位置处发射的激光束时确定扫描开始时刻。这种布置允许激光二极管避免一次又一次地浪费时间，作为用于稳定用于执行APC的激光束和用于识别扫描开始定时的上升时间，并且尽可能长地确保持续时间。因此，可以在足够的持续时间内适当地对激光二极管执行APC，并且同时可以通过检测稳定的激光束来精确地确定扫描开始定时。

摘要： An optical scanner includes a light source, optical deflector, mirror, first photosensitive drum, and second photosensitive drum. The light source emits a first light beam and a second light beam. The optical deflector deflects the first light beam and the second light beam. The mirror has a reflecting part that reflects the deflected first light beam and a passing part that passes the deflected second light beam. The passing part is displaced from the reflecting part. The first photosensitive drum performs a development with a first toner having a first color. The reflected first light beam scans the first photosensitive drum in a main scanning direction. The second photosensitive drum performs a development with a second toner having a second color different from the first color. The passed second light beam scans the second photosensitive drum in the main scanning direction. The first photosensitive drum and second photosensitive drum are arranged in a sub scanning direction orthogonal to the main scanning direction.

摘要： The print permitting ratios of the masks in the first to fourth passes of a C ink are respectively 6.2%, 37.5%, 37.5%, and 18.8%. On the other hand, the print permitting ratios of the masks in the first to fourth passes of an M ink are respectively 12.5%, 37.5%, 37.5%, and 12.5%. In this way, the respective masks are set such that a larger amount of the C ink is applied in a later pass as compared with the M ink. Thereby, it is possible to reduce an amount of the M ink to be applied later with respect to the C ink functioning to “reduce a permeation speed of an ink applied later by filling,” and it is possible to prevent a permeation speed from slowing down overall. As a result, it is possible to prevent the occurrence of beading due to a time to complete permeation becoming longer.

摘要： In an image forming apparatus, a rigid-body plate, which is to be placed across a scanning unit for constituting a housing, also serves as an upper cover of the scanning unit, and the scanning unit is suspended on the rigid-body plate at an interior position from a top cover of an upper portion of the housing of the image forming apparatus. This obviates a necessity for interposing, between the scanning unit and a photosensitive drum, a rigid-body plate or the like used for mounting the scanning unit, thereby shortening a distance between the scanning unit and the photosensitive drum.
