Image forming apparatus for executing secure print job

An image forming apparatus comprising:

• a printing device;
• a controller that controls the printing device;
• and
• a print job management unit that executes a secure print job by the controller based on a job request from a user,
• wherein the controller executes calibration of the printing device when the controller detects that a predetermined parameter measured from a previous calibration exceeds a predetermined value, and
• wherein the print job management unit, upon receiving a job request for the secure print job, determines whether or not a difference between a current value of the predetermined parameter and the predetermined value is less than a predetermined threshold, and if the difference is less than the predetermined threshold, the print job management unit determines whether to cancel the secure print job in accordance with a predetermined setting data that indicates whether or not the user selects job execution permission.
