Abstract
A lifespan determination device determines a lifespan of a fixing unit including a heating member and a pressing member and fixing a toner image onto a sheet passing through a feed area therebetween. The device includes a counting unit, a determining unit, and a notifying unit. The counting unit includes counters for respective sheet widths and adds, to a count value of a counter corresponding to a sheet width of the fed sheet, a count value obtained by multiplying the number of fed sheets having the sheet width by a first weight coefficient corresponding to a degree of damage given to the fixing unit by the fed sheet. The determining unit determines whether or not a count value of any one of the counters has reached a predetermined value. The notifying unit provides a notification indicating that the lifespan is reached if the count value has reached the predetermined value.
