PURPOSE:To make sure of an image forming state as well as to aim at reduction in defective copies, by installing an image checking means such as a transparent window or the like, in an uppermost stage bin among plural bins. CONSTITUTION:Plural bibs 20a-20n are moved up and down according to the number of designated copy sheets and the specified pages are arranged in consecutive order from the uppermost stage bin 20a. A top plate of this uppermost stage bin 20a is formed with a transparaent plastic plate 21, whereby an image state of a sheet 30 to be housed is made so as to be checkable from the outside. Therefore, the first copy image state is confirmed, and if there is a copy defective, correction of the defective state can be done at once by copy operation, thus defective copies are reducible.
