发明名称 IMAGE FORMING APPARATUS
摘要 An image forming apparatus including: a light irradiating unit configured to irradiate a photosensitive member charged by a charging unit with light to form an electrostatic latent image; a processing unit configured to generate M-bit (M is an integer not less than 2) density data indicating a density based on the input image data, to generate (M+N)-bit processing data based on the M-bit density data and N-bit (N is an integer not less than 1) correction data, to convert the processing data into a plural-bit binary drive data corresponding to a value of the processing data, and to serially output the plural-bit drive data bit by bit to generate a drive signal; and a drive unit configured to drive the light irradiating unit based on the drive signal.

主权项 1. An image forming apparatus configured to form an image based on input image data, the image forming apparatus comprising: a photosensitive member; a charging unit configured to charge the photosensitive member; a light irradiating unit configured to irradiate the photosensitive member charged by the charging unit with light; a developing unit configured to develop an electrostatic latent image with toner, the electrostatic latent image being formed on the photosensitive member by the light irradiating unit irradiating the photosensitive member; a processing unit configured to generate M-bit (M is an integer equal to or larger than 2) density data indicating a density based on the input image data, configured to generate (M+N)-bit processing data based on the M-bit density data and N-bit (N is an integer equal to or larger than 1) correction data, configured to convert the (M+N)-bit processing data into a plural-bit binary drive data corresponding to a value of the (M+N)-bit processing data, and configured to serially output the plural-bit binary drive data bit by bit to generate a drive signal; and a drive unit configured to drive the light irradiating unit based on the drive signal generated by the processing unit.
