PROBLEM TO BE SOLVED: To provide an image processing method, an image processing apparatus, an image forming apparatus, an image reading apparatus, a computer program, and a recording medium in which image processing is performed by discriminating the feature of a pixel per line. SOLUTION: After initialization is performed (S11), an available image area is recognized from information, including a read start position and a read end position of a document, a scaling for performing image processing, a processing object position, or the like (S12). Subsequently, the number of chromatic pixels of one line is counted to output it to a memory (S16), and when it is summed up to an end line of the available image area (S17:YES), a difference between a count number N1 in one previous line of the available image area and a count number N2 in the end line of the available image area is calculated (S19) to thereby compare the difference with a predetermined threshold value (S20). When the difference is larger than the threshold (S20:YES), it is determined to be a chromatic image (S21), whereas when the difference is smaller than the threshold (S20:NO), it is determined to be an achromatic image (S22).
