摘要：
An image forming apparatus includes: a light source; and a light source control unit that supplies a pulse drive current according to image data to the light source. An amplitude of a part of the drive current corresponding to a specified pixel of the image data is larger than an amplitude of a part of the drive current corresponding to a normal pixel of the image data that is a pixel other than the specified pixel and the pulse width of the part of the drive current corresponding to the specified pixel is smaller than the pulse width of the part of the drive current corresponding to the normal pixel.
