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.

Abstract: A film member in a development device can vibrate with respect to an internal wall in the development device. An idler gear in the development device includes a projection and is reciprocally movable between a first position and a second position. The first position is a position where the projection is apart from an end edge of the film member in response to a rotation of a toner supply roller when image formation is performed. The second position is a position where the projection overlaps with the end edge of the film member in response to a reverse rotation of the toner supply roller when image formation is not performed. The projection causes the film member to vibrate by intermittently coming into contact with the end edge of the film member along with a rotation of the idler gear at the second position.

Abstract: A developer transporting mechanism includes a pipe-like transporting path, sealing member, shutter, and urging member. The pipe-like transporting path, through which a developer is transported, has an discharge port at part of its side surface. The shutter is slidable along the surface of the sealing member to open and close the discharge port. The urging member urges the shutter in a direction in which the discharge port is closed. The sealing member is secured to the outer circumferential surface of the pipe-like transporting path. The sealing member also has a reduced part; its dimension in a width direction orthogonal to a direction in which the shutter moves is gradually reduced from the upstream end in the closing direction of the shutter toward the downstream end.
