    摘要： An optical writing device writes an image on a photoconductor with light emitted from a light-emitting element array including a plurality of light-emitting elements lined in one direction. The optical writing device includes: a thinning unit that thins pixels in input binary image data depending on a pattern of the image data; a thinning rate setting unit that sets a thinning rate by the thinning unit for each predetermined range of the image data; and a light-emitting time changing unit that changes a light-emitting time of the light-emitting element array for each predetermined range of the binary image data thinned by the thinning unit depending on the thinning rate set by the thinning rate setting unit and a set toner saving rate.

    摘要翻译： 光写入装置将光从一个方向排列的多个发光元件的发光元件阵列发出的光写入光电导体。 光写入装置包括：稀疏单元，其根据图像数据的图案使输入的二进制图像数据中的像素成像; 稀疏率设置单元，用于通过所述稀疏单元针对所述图像数据的每个预定范围设置稀疏率; 以及发光时间改变单元，其根据由稀疏率设定单元设定的变稀率，对由稀疏单元稀疏的二值图像数据的每个预定范围的发光时间改变发光时间， 设定墨粉节省率。
