a conveying path forming portion configured to form a conveying path of developer, the conveying path including a conveying inlet through which developer enters and a conveying outlet through which developer is discharged to outside of the developer replenishing device;
a moving member including a holding portion configured to hold developer supplied from the containing portion, the moving member being configured to be movable to a first position at which the holding portion is connected to the containing portion, and a second position at which the holding portion is connected to the conveying inlet of the conveying path;
an exhaust air portion configured to generate exhaust air; and
a filter configured to pass air flow and not to pass developer, wherein
in a case where the moving member is at the second position, the filter is disposed such that developer is held inside the holding portion, and exhaust air generated by the exhaust air portion is allowed to enter the holding portion, and the holding portion is located below the conveying inlet in a gravity direction.
