An image processing apparatus includes a plurality of detecting units each of which detects whether binary signals derived from picture elements of image data match with one of a plurality of patterns of isolated dots, the detecting units generating a plurality of detection signals which are set based on respective results of the detections with respect to the isolated-dot patterns, wherein the isolated-dot patterns are different from each other in the number of isolated dots included in each pattern, the isolated-dot patterns having respective sizes predetermined for isolated-dot removing function levels. A selecting unit selects one of the isolated-dot removing function levels in response to an operation control signal, the selecting unit generating an isolated-dot signal which is set for each picture element based on the detection signals by the selected isolated-dot removing function level. An operation control part inputs the operation control signal to the selecting unit in accordance with a setting by an operator with respect to one of the isolated-dot removing function levels.
