A developing device includes a developer bearer and a stirring conveyor. The stirring conveyor includes a first conveying chamber including a conveying member and a second conveying chamber to receive the developer from an end of the first conveying chamber. The conveying member includes a forward winding blade, a reverse winding blade, and a shaft portion on which the forward winding blade and the reverse winding blade are mounted with a space therebetween. A circumferential phase of the conveying member at a start position of the reverse winding blade is different from a circumferential phase of the conveying member at an end position of the forward winding blade. The conveying member is disposed in the first conveying chamber so that the space is opposite a portion at which the second conveying chamber receives the developer from the end of the first conveying chamber.

A toner container includes a cylindrical container body having a head with an opening in the head, a cap into which the head of the container body is inserted, and a sheet member attached inside the cap. The cylindrical container body rotates around a rotation axis extending in a longitudinal direction of the container body to transport toner contained in the container body toward the opening. The cap has a toner outlet through which the toner discharged from the opening is discharged outside the toner container. The sheet member includes a first elastic-deformation portion that is elastically deformable and located near the toner outlet, and a second elastic-deformation portion that is elastically deformable and located in the container body and near the opening.
