Abstract
An image processing circuit board, a reading device, an image forming apparatus, an image processing method, and an image processing device. The image processing circuit board subtracts output of an image sensor when no input light is received, from output of a reading device that reads image data of a subject using the image sensor, discriminates between effective area and invalid area of the image data output by the reading device, and converts the image data of the invalid area into a predetermined output value after the output of the image sensor when no input light is received is subtracted from the output of the reading device.
