Abstract
An image processing apparatus includes an acquisition unit, a first detection unit, a first determination unit, a second detection unit, a second determination unit, a correction unit, and a transmitting unit. The acquisition unit acquires image information having multiple pixels. The first detection unit detects sub-scanning-direction boundary pixels in accordance with the image information. The first determination unit determines whether or not a development-related defect occurs in a preset number of pixels downstream of the sub-scanning-direction boundary pixels in the sub-scanning direction. The second detection unit detects an end pixel in the main scanning direction. The second determination unit determines whether or not each of sub-scanning-direction boundary pixels arranged in the main scanning direction is close to the end pixel in the main scanning direction. The correction unit corrects the image information. The transmitting unit transmits the image information corrected by the correction unit to an image forming apparatus.
