A toner transport apparatus that transports toner particles and includes a lateral transport device and a longitudinal transport device. The lateral transport device includes a lateral tube extending in a lateral direction and a lateral transport member provided inside the lateral tube in a rotatable manner and transporting toner particles. The longitudinal transport device includes a longitudinal tube coupled to an end of the lateral tube and extending in a longitudinal direction and a longitudinal transport member provided inside the longitudinal tube in a rotatable manner and transporting toner particles downward, and thereby transports the toner particles transported from the lateral transport device downward. An end portion of the lateral transport member on a downstream side in a toner transport direction extends to an inside of the longitudinal tube.
