Image forming apparatus having print job time display and image quality adjustment control

An image forming apparatus, comprising:

• a printer configured to form an image on a sheet;
• a display configured to display a remaining time in which a print job is not performed by the printer in a case where an image quality adjustment control for adjusting a parameter of the printer is performed, the remaining time being counted down;
• a processor configured to execute instructions to:
• perform a first image quality adjustment control;
• perform a second image quality adjustment control different from the first image quality adjustment control;
• control whether or not to perform the first image quality adjustment control repeatedly;
• determine the remaining time based on a first time corresponding to the first image quality adjustment control and a second time corresponding to the second image quality adjustment control in a case where the first image quality adjustment control and the second image quality adjustment control are continuously performed after the printer finishes performing a print job, wherein the processor determines again the remaining time based on the second time before the second image quality adjustment control is performed in the case where the first image quality adjustment control and the second image quality adjustment control are continuously performed after the printer finishes performing the print job;
• and
• determine the remaining time based on a third time corresponding to the first image quality adjustment control and the second time corresponding to the second image quality adjustment control in a case where the first image quality adjustment control and the second image quality adjustment control are continuously performed by interrupting a print job, the third time being shorter than the first time, wherein the processor determines again the remaining time based on the second time before the second image quality adjustment control is performed in the case where the first image quality adjustment control and the second image quality adjustment control are continuously performed by interrupting the print job.
