摘要： A toner resupply device having: a detector plate for detecting a surface of toner stored in a hopper; a douser that moves together with the detector plate; a fixing plate for fixing the detector plate and the douser integrally; and a toner sensor for detecting a phase of the douser. The douser has a light-blocking surface that blocks and transmits light to be detected by the toner sensor, and a shaft extending in an axial direction crossing the light-blocking surface, the shaft being inserted in a hole made in the detector plate. The shaft has a groove in which the fixing plate is locked, the groove extending in a direction crossing the axial direction. The fixing plate in a state of being locked in the groove pushes the shaft in the axial direction, thereby fixing the detector plate and the douser to each other.

摘要： A supplying roller supplies toner to a developing roller which develops the electrostatic latent image formed on a photoconductive drum. The controller controls the supply to output first and second voltages to the developing roller and supplying roller. A detector generates a signal indicative of remaining toner. The voltage controller performs voltage correction according to the signal either in a first mode where the first voltage has a smaller value when the signal has become below a reference than when the signal is above the reference, or in a second mode where the first voltage has a smaller value when the signal has become below the reference than when the signal is above the reference, and a difference between the first and second voltages has a larger value when the signal has become below the reference than when the signal is above the reference.
