An image processing apparatus for color image formation that adds a specific pattern to identify the apparatus more reliably, to image information. For example, in a bit array of a printer's identification number in binary representation, if one bit has a value "0", the value of input multivalued image data in a M-th line in a subscanning direction is decremented by "30". On the other hand, if the bit value is "1", the data of the input multivalued image data is incremented by "30". If the data value has been incremented by "30" in the M-th line, data value at a position immediately below the position where the data valued has been incremented (decremented) in the next (M+1)-th line is decremented by "30", while if the data value has been decremented by "30" in the M-th line, data value at a position immediately below the position where the data value has been incremented (decremented) in the next (M+1)-th line is incremented by "30".
