An image forming apparatus including: a sheet feeding roller which feeds a sheet accumulated on a tray; and a hardware processor which: detects a movement speed of the sheet currently fed by the sheet feeding roller; and calculates a difference amount between the movement speed and a first reference speed, and determines a life of the sheet feeding roller based on the difference amount, wherein the hardware processor determines whether or not to use the movement speed of a first sheet for life determination based on a relationship between the movement speed of the first sheet and the movement speed of a sheet fed before the first sheet, and if the hardware processor determines not to use the movement speed of the first sheet for the life determination, the hardware processor calculates the difference amount by excluding the movement speed of the first sheet.
