An image processing apparatus includes a reading unit, a determining unit, a converting unit, a recording unit, and a control unit. The reading unit moves sensors corresponding to a predetermined number of pixels aligned along a sub-scanning direction in a main scanning direction to read an image having a predetermined width of an original. The determining unit determines an area designated by a marker in the original in accordance with pixel data of a pixel read by the reading unit and pixel data of pixels surrounding the pixel. The converting unit converts the pixel data of the pixel read by the reading unit in accordance with a determination result from the determining unit. The recording unit drives recording elements corresponding to the predetermined number of pixels aligned along the sub-scanning direction in accordance with pixel data from the converting unit and moving the recording elements in the main scanning direction to record the image having the predetermined width on a sheet. The control unit moves the reading unit in the sub-scanning direction by a distance corresponding to pixels less than the predetermined number of pixels to perform a next main scanning operation after the reading unit completes a main scanning operation.
