摘要	An optical writing apparatus includes a light source device that includes a VCSEL having an alignment of at least two channels in a sub scanning direction configured to emit plural light beams in a block. A deflector deflects the plural light beams toward an image bearer that forms an image by changing a line speed of image formation. A control device decreases a number of light beams by turning off a prescribed same number of the channels symmetrically from the both ends of the alignment in accordance with the line speed.
其他摘要	一种光学写入装置，包括光源装置，该光源装置包括VCSEL，该VCSEL具有在副扫描方向上的至少两个通道的对准，所述子扫描方向被配置为在块中发射多个光束。偏转器通过改变图像形成的线速度使多个光束朝向形成图像的图像承载体偏转。控制装置通过根据线速度从对准的两端对称地关闭规定的相同数量的通道来减少光束的数量。
