<p>A toner supplying device (1) includes: a toner container (2) that is tubular, includes a spiral groove (21) at an outer circumferential face (2d), a toner discharge opening (22) at one end (2a) in a longitudinal direction (D), and a depression (23) at the other end (2b) in the longitudinal direction (D), and is rotationally driven to convey toner contained in the toner container (2) along the spiral groove (21) in the longitudinal direction (D) to discharge the toner from the toner discharge opening (22); a rotational driving unit (200) that engages with the one end (2a) of the toner container (2) to rotationally drive the toner container (2) to cause the toner container (2) to discharge the toner; and a projection (52, 152) provided at an interior portion (50) at which the toner container (2) is installed, and having an inclination (52a, 152a) in which a projection amount increases toward downstream in a rotational direction of the toner container (2). The projection (52, 152) is formed to fall in the depression (23) of the toner container (2).</p> |
