Image forming apparatus and non-transitory computer readable medium

An image forming apparatus comprising:

• a first rotating body pair that transports a recording medium;
• a second rotating body pair that transports the recording medium transported by the first rotating body pair;
• a first detection unit that detects the recording medium at a first position in a transporting width direction of the recording medium, the transporting width direction being a direction that is perpendicular to a transporting direction of the recording medium;
• a second detection unit that detects the recording medium at a second position, the second position being different from the first position in the transporting width direction;
• and
• a modification unit that modifies a shape of an image to be formed on the recording medium in accordance with a difference between a detection time during which the recording medium is detected at the first position and a detection time during which the recording medium is detected at the second position.
