Abstract
A driving force transmitting apparatus includes first and second planetary gear units and switching and urging members. The first planetary gear unit includes a first mesh gear and a first locked gear provided with first locked portions. The second planetary gear unit includes a second locked gear provided with second locked portions, and a second mesh gear meshing with the first mesh gear. The switching member includes first and second locking portions and can move to (i) a first stop position at which the first locking portion stop the first locked gear, and, urged by the urging member, (ii) a second stop position at which the second locking portion stops the second locked gear. An interval between the second locked portions in a rotational direction of the second locked gear is larger than an interval between the first locked portions in a rotational direction of the first locked gear.
