A developing device includes a developer storage container, a remaining amount detecting portion, an agitating portion, a contact member, and a support portion. The agitating portion is configured to be rotated to thereby agitate the developer. The contact member is attached to the agitating portion, and is configured to, when the agitating portion is rotated in a predetermined first rotational direction, move in the first rotational direction and make contact with a sensing surface. The support portion is attached to the agitating portion, and is configured to, when the agitating portion is rotated in the first rotational direction, support the contact member in a first position where the contact member can make contact with the sensing surface, and, when the agitating portion is rotated in a second rotational direction opposite to the first rotational direction, support the contact member in a second position distant from the sensing surface. |
