Abstract
A developing device includes a stirring member including a flexible sheet member having a first sheet portion and a second sheet portion overlapping each other with respect to a thickness direction of the sheet member. With respect to a lateral direction of the sheet member which is a direction from a fixed end fixed to a rotating shaft portion to the free end, a length of the first sheet portion is longer than a length of the second sheet portion, and when the stirring member is rotated, a free end of the first sheet portion is capable of contacting an inner wall surface of a toner accommodation chamber. The sheet member is provided with a through hole penetrating in a thickness direction of the sheet member in a region where the first sheet portion and the second sheet portion overlap each other.
