A support element for supporting a coil spring that rotates to transport toner, and transmitting a rotational force of driving means to the coil spring. The support element includes: an end inserting member with a recess in which an end portion of the coil spring is inserted; a first support member, a second support member with a projection, a third support member, and a fourth support member, which support non-end portions of a first coil spring; and joint members for joining the end inserting member and the support members. This realizes a coil spring support element with which the flow rate of toner from a toner bottle can be increased, and the rotational force of driving means such as a motor can be efficiently transmitted to the coil spring.
