An image forming apparatus for use with a transfer sheet includes: a sheet feeding unit structured to feed the transfer sheet; a color detection sensor structured to detect color information on the transfer sheet fed from the sheet feeding unit; a recognition section structured to recognize whether the transfer sheet subjected to the detection by the color detection sensor is a non-tabbed transfer sheet having no tab, or either a tabbed transfer sheet having a tab or an unprocessed tabbed transfer sheet blank, the unprocessed tabbed transfer sheet blank being capable of being processed into a tabbed transfer sheet having a tab by post-processing, wherein a recognition result is made based on the color information detected by the color detection sensor; and a control section that controls image forming on and conveying of the fed transfer sheet, according to the recognition result by the recognition section.
