A paper feeding device includes a stacking plate for stacking sheets. The stacking plate is movable vertically within a range from a lower limit position to a pick-up position. The stacking plate has a first surface facing the lower limit position and a second surface facing the pick-up position. The paper feeding device also includes a driving device for driving the stacking plate. The paper feeding device has a locking member for locking the staking plate in the lower limit position. The locking member has a deformable section for contact with the second surface of the stacking plate. The deformable section becomes deformed by a driving force applied through the stacking plate as locked in the lower limit position by the driving device, to unlock the stacking plate.

Moving member holding mechanism, paper feeding device, and image forming apparatus

In one embodiment, a charge removal member, which removes static electricity built up on paper waste, is disposed in a collecting containerused for collecting the punch wastegenerated by punching transported paper. The charge removal memberis disposed in an open top portion of the collecting container, in a location corresponding to a hole-punching punchdisposed in the punching unit, with a proximal end portionof the charge removal membersupported by the collecting containerand the distal end portion of the charge removal memberforming charge removal comb-shaped needlesextending towards the central portion of the collecting container.
