A developing apparatus includes a first conveying member and a second conveying member shorter than the first conveying member. In a rotational direction of the rotation shaft, the second conveying member is disposed upstream of the first conveying member, with the fixed end of the second conveying member and the fixed end of the first conveying member placed one on another. The free length of the second conveying member at a first position, a second position, and a third position, which sequentially distance away from the driving transmission member in the axial direction of the rotation shaft, sequentially becomes larger.
