A toner conveying device includes a container, a rotating member having a protruding portion inside the container, and a stirring member of toner. A first region and a second region on the opposite side are provided inside the rotation trajectory of the rotating member in a state without contact with the inner surface of the container. The protruding portion is provided between a first position in which a second straight line that is perpendicular to a first straight line that divides the rotation trajectory and passes through the center of the rotating member and is in the second region, and a second position in which a third straight line that is perpendicular to a contact line passing through a contact point between the container and the stirring member, passes through the center at the time of deformation of the stirring member and is in the second region.
