Abstract
A seal member includes a first seal portion abutting an end portion of a rotating body to seal a gap between a storage container and the end portion, and a second seal portion abutting an end portion of a blade to seal a gap between the storage container and the end portion. The second seal portion has a tip contacting portion to contact a tip portion of the blade and a non-tip contacting portion to contact a portion of the blade except for the tip portion. The non-tip contacting portion is recessed to form a step between the non-tip contacting portion and the tip contacting portion. The tip contacting portion includes a base portion to contact with the storage container, an abutting portion configured to abut the blade, and a connecting portion which connects the base portion and the abutting portion to each other.
