Abstract
A toner conveying device includes a case storing toner; a conveyance member rotatably supported at both ends by the case, including a spiral blade extending along a rotational axis, and configured to rotate to convey the toner inside the case in a predetermined conveying direction; and a pushing member pushed against an outer peripheral portion of the conveyance member in a first direction intersecting with the rotational axis and configured to slide on the outer peripheral portion as the conveyance member rotates. The pushing member is composed of a flexible sheet member and includes a base portion secured at a securing position inside the case and protruding pieces aligned along the rotational axis and protruding from the base portion toward the conveyance member to abut on the outer peripheral portion. An alignment interval between the protruding pieces is different from a pitch of the spiral blade along the rotational axis.
