An image forming apparatus comprising:
- an image forming unit configured to form an image;
- and
- a control unit configured to control timing to send a signal to request image information for causing the image forming unit to form an image,
- wherein the control unit controls the timing to send the signal to request the image information according to information on a margin from a leading end of a recording medium to a leading end of the image formed on the recording medium in a conveying direction of the recording medium so that the timing to send the signal to request the image information is earlier than timing to request predetermined image information after preparation for forming an image is completed.
