Image processing apparatus and image processing method

A non-transitory recording medium storing a computer readable program used in an image processing apparatus including:

• an image processing unit configured to execute image processing including skew correction that deforms an image so as to cancel distortion generated on the image formed on a sheet;
• and
• a control unit configured to control the image processing on the image processing unit,
• wherein, in a case where a margin amount available for correcting the distortion is defined as a first correction margin amount and a margin amount used for correction other than for skew correction, among the distortion, is defined as a second correction margin amount, a third margin amount is calculated by subtracting the second correction margin amount from the first correction margin amount, and
• the image processing unit executes the image processing including the skew correction toward a first image formed on a first surface of the sheet and toward a second image formed on a second surface of the sheet such that the skew correction amount to be corrected by the skew correction falls within a range of the third correction margin amount.
