Abstract
A developing apparatus includes a developer conveyance member including a rotatably supported flexible sheet having a first distance between its rotation axis and an edge of the flexible sheet in a state where the flexible sheet is unbent. A lid of a developing container includes a corner portion that extends a storage space outward of an imaginary circle with a radius of the first distance centered on the rotational axis, and a contact portion which protrudes from an inner surface of the corner portion to an inner side of the imaginary circle and with which the flexible sheet contacts while the conveyance member is being rotated. The contact portion has a distal edge shaped such that a distance between the distal edge and the rotation axis increases toward a downstream side in a rotation direction of the conveyance member as viewed in the direction along the rotation axis.
