description PROBLEM TO BE SOLVED: To suppress the occurrence of erroneous determination less than the conventional one in determining the progress degree of deterioration of a separation roller 45b. SOLUTION: A deterioration determining device includes information acquisition means acquiring information whether or not the separation roller 45b is in the initial condition, and a control section. The control section performs, for a predetermined time period after the start of use from the initial condition, a processing for storing the detection result of the accumulative rotation angle of the separation roller 45b in a flash memory, accumulated when recording sheets are passed through the nip made by the abutment between a paper feed roller 45a and the separation roller 45b, based on the acquisition of the information to be in an initial condition, by the information acquisition means. Based on the detection result stored in the predetermined time period, the control section performs a processing for constructing a reference transfer average A of the accumulative rotation angle.
