1. An image forming apparatus comprising:
an image forming device configured to form an image on a sheet;
a fixing device including a fixing member to fix the image formed on the sheet and a polishing device to polish a surface of the fixing member; and
circuitry configured to:
determine whether an interruption required operation is to be performed, at a time while image formation is being performed by the image forming device to execute an image forming job, or at a time after image formation is executed for one job and before image formation is to be executed for a subsequent job,
control the image forming device to stop image formation to perform the interruption required operation, based on a determination indicating that the interruption required operation is to be performed,
control the polishing device to polish the surface of the fixing member concurrently with the interruption required operation;
acquire information indicating a surface roughness of the fixing member, and
control the polishing device to polish the surface of the fixing member concurrently with the interruption required operation in response to the acquired surface roughness exceeding a second threshold that is less than a first threshold,
the first threshold causing the polishing device to polish the surface of the fixing member after stopping image formation.
