To provide a toner replenishing device capable of detecting a toner remaining amount accurately even if the capacity of a toner container is smaller than that of the conventional one when a detection surface of a toner detection sensor that detects the toner remaining amount in the toner container is cleaned and to provide an image forming apparatus including the toner replenishing device.
The toner replenishing device includes: the sub-hopper (toner container) 48 that contains toner; the toner detection sensor 72 that is set on a wall surface in the sub-hopper 48 and detects whether the toner remains at a set height; and an agitator 74 that rotates in the sub-hopper 48 and cleans a detection surface 721 of the toner detection sensor 72. The toner replenishing device further includes a paddle 75 that collects toner to a vicinity of the detection surface of the toner detection sensor 72 in the sub-hopper 48.
