Abstract
An automatic sheet feeding apparatus for use in a copying machine and the like having a sheet separating members. The separating members include a sheet feeding rotatable member, a separating rotatable member and a follower rotatable member, with the feeding rotatable member in contact with both the separating member and the follower rotatable member. The feeding rotatable member has a peripheral surface which is harder than that of the separating rotatable member. The follower rotatable member has its peripheral surface of a material having a coefficient of friction smaller than that of the other members. The width of the contact area between the separating rotatable member and feeding rotatable member is larger than that between the follower rotatable member and the feeding rotatable member.
