摘要： PROBLEM TO BE SOLVED: To obtain an image forming apparatus capable of suppressing occurrence of an image defect due to scars or stripes on a surface of a fixing member even if there is no operational input from a user.
SOLUTION: When an image forming step is finished, paper length, paper width and basis weight are acquired as information related to a sheet member P on which an image has been formed in the finished image forming step (300). A belt damage amount is calculated on the basis of the acquired paper length, paper width and basis weight (302), and a belt damage cumulative amount is updated (304). Whether or not the updated belt damage cumulative amount is equal to or above a threshold is determined (306). When the belt damage cumulative amount is equal to or above the threshold, it is determined as a situation in which a condition required when performing surface adjusting operation is fulfilled, and the surface adjusting operation of the fixing belt is designated to be performed (308).
