Abstract:
1. An image forming apparatus, comprising: a driving component to rotate a driving assembling member about a rotational driving axial line; a developing unit detachably provided in the image forming apparatus that has a driven assembling member capable of being engaged with and disengaged from the driving assembling member in a direction of the rotational driving axial line; a power transmission unit to selectively engage a mechanical power to the developing unit; and a manipulating unit to manipulate the power transmission unit, wherein the power transmission unit is disposed between the driving assembling member and the driven assembling member and enables at least one of the driving assembling member and the driven assembling member to move in the direction of the rotational driving axial line, and the driven assembling member is rotated about the rotational driving axial line by the driving component when the driven assembling member and the driving assembling member are engaged, wherein at least one of the driving assembling member and the driven assembling member is elastically pressurized toward the other of the driven assembling member and the driving assembling member.
