The take-up spool is driven in a first direction about a longitudinal axis of the take-up spool during an automatic loading and in a second direction counter to the first direction about the longitudinal axis of the take-up spool during an image forming operation. The leader sheet has a leading end which is wound around and secured to the take-up spool then driven in the first direction, and the remainder of the leader sheet is folded backwards along a score line, defined therein, to overlay the leading end. The leading end of the leader sheet is formed with at least one through-hole for connection of the remainder of the leader sheet with the adhesive region on the take-up spoon through the through-hole after it has been folded backwards.
