Abstract
A toner supply device includes a toner guide, an opening and closing member, and a biasing member. The toner guide guides toner toward a toner supply port. The opening and closing member opens and closes the toner supply port by moving. The biasing member biases the opening and closing member in a closing direction. The opening and closing member includes a base portion, an extension portion, and a toner receiving portion. The base portion faces and closes the toner supply port at the closing position. The extension portion extends downward from an edge of an end portion of the base portion, wherein the edge faces in the closing direction. The toner receiving portion is contracted upon receiving a pressing force in an opening direction, and is expanded upon disappearing of the pressing force and receives toner that has fallen down from the end portion of the base portion.
