Summary:To provide a technique capable of quickly determining that the toner in the developer container is empty.SOLUTION: The toner transfer device includes: a storage part for storing toner used in a development unit; and a receiving part for receiving the toner emitted from an outlet that sends out the toner from the storage part. The toner transfer device further includes: a transport path part that constitutes a transport path for transporting the toner to the development unit, and an optical sensor unit that detects the presence or absence of toner in the passing area where the toner is falling after the toner is emitted from the outlet.SELECTED DRAWING: Figure 1 【課題】現像剤容器内のトナーが空になったことを迅速に判定する技術を提供する。【解決手段】現像装置に用いられるトナーを収容する収容部と、収容部からトナーを送り出す出射口から出射されたトナーを受け入れる受入部を含み、当該トナーを現像装置に搬送するための搬送経路を構成する搬送経路部と、出射口からトナーが出射されたあとでトナーが落下する途中の通過領域におけるトナーの有無を検知する光センサー部を備えるトナー搬送装置を用いる。【選択図】図１
