<p>A toner resupply device having: a detector plate (40) for detecting a surface of toner stored in a hopper (26); a douser (50) that moves together with the detector plate (40); a fixing plate (60) for fixing the detector plate (40) and the douser (50) integrally; and a toner sensor (SE) for detecting a phase of the douser (50). The douser (50) has a light-blocking surface (52) that blocks and transmits light to be detected by the toner sensor (SE), and a shaft (51) extending in an axial direction crossing the light-blocking surface (52), the shaft (51) being inserted in a hole (43a) made in the detector plate (40). The shaft (51) has a groove (53) in which the fixing plate (60) is locked, the groove (53) extending in a direction crossing the axial direction. The fixing plate (60) in a state of being locked in the groove (53) pushes the shaft (51) in the axial direction, thereby fixing the detector plate (40) and the douser (50) to each other.</p> |
