Abstract: An example image forming apparatus includes a communicator to receive print data, an image forming unit, and a processor to control the image forming unit to perform image processing on the received print data and control the image forming unit to print the image-processed print data. When the received print data is not a scan file, the image processing is performed at a first level and when the received print data is a scan file, the image processing is performed at a second level, the second level being higher than the first level.

Abstract: An image forming apparatus is provided. The image forming apparatus includes an image former to change a transfer condition while printing a calibration chart in which patches of different colors are repeatedly arranged in a sub-scanning direction, a scanner to scan the printed calibration chart, and a processor to determine an image defect under each transfer condition using the scanned calibration chart, and to set a transfer condition of the image former based on the determined image defect.
