摘要：
An over-stack protective portion is provided on a stopper member. When a sheet feeding device is in a standby position, the over-stack protective portion is held in a position in which the over-stack protective portion is in pressure contact with sheets having the maximum stacking height capable of being fed and supported by a sheet supporting portion. Also, when the sheets are to be fed, the pressure contact of the over-stack protective portion with the sheets having the maximum stacking height is released.
