IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD

摘要

An image forming apparatus includes a drive signal generating unit that generates a drive signal for driving a light source based on a reference pulse signal serving as a reference to form a plurality of pixels arranged in the main-scanning direction of an image, and the drive signal generating unit generates the drive signal by adjusting the pulse width of the reference pulse signal so that the amplitude of portions of the reference pulse signal with the adjusted pulse width corresponding to specific pixels among the pixels is larger than the amplitude of portions corresponding to normal pixels that are pixels other than the specific pixels among the pixels, and so that the pulse width of the portions of the reference pulse signal with the adjusted pulse width corresponding to the specific pixels is smaller than the pulse width of the portions corresponding to the normal pixels.

1. An image forming apparatus that forms an image by scanning an image bearer with light modulated based on image information, the image forming apparatus comprising:
a light source that emits the light; and a drive signal generating unit that generates a drive signal for driving the light source based on a reference pulse signal serving as a reference to form a plurality of pixels arranged in a main-scanning direction of the image, wherein the drive signal generating unit generates the drive signal by adjusting a pulse width of the reference pulse signal so that an amplitude of a portion or portions of the reference pulse signal with the adjusted pulse width corresponding to a specific pixel or pixels among the pixels is larger than an amplitude of a portion or portions of the reference pulse signal with the adjusted pulse width corresponding to a normal pixel or pixels that is/are a pixel or pixels other than the specific pixel or pixels among the pixels, and so that the pulse width of the portion or portions of the reference pulse signal with the adjusted pulse width corresponding to the specific pixel or pixels is smaller than a pulse width of the portion or portions of the reference pulse signal with the adjusted pulse width corresponding to the normal pixel or pixels.
