Abstract:
1. An image forming apparatus that forms a color image by layering toner images of different colors, the image forming apparatus comprising: a photoreceptor on which an electrostatic latent image is formed through charging and exposure; an exposure unit that performs exposure-scanning on a surface of the photoreceptor in accordance with an image signal input thereto; an intensity determination unit that determines exposure intensity of the exposure unit according to an image forming condition; and a timing determination unit that determines an input timing at which an image signal is to be input to the exposure unit for each scanning line, wherein the exposure unit has a delay duration that differs depending on the exposure intensity, the delay duration being a duration from input of an image signal of each pixel to be exposed in each scanning line on the surface of the photoreceptor to start of exposure of the pixel at the determined exposure intensity, and the timing determination unit obtains the delay duration corresponding to the determined exposure intensity, and determines the input timing such that input of an image signal of an initial pixel to be initially exposed in each scanning line on the surface of the photoreceptor is delayed by a predetermined time before exposure of the initial pixel is started, the predetermined time being based on a scanning start position and a light emission delay duration.
