ABSTRACT:
An in-liquid turn bar disposed in a developing tank includes a first cylindrical member disposed outside and a second cylindrical member disposed inside. In the first cylindrical member, plural slit-shaped discharge openings for discharging the developer along a longitudinal direction are formed. In the second cylindrical member, plural nozzle holes for ejecting the developer are formed. A pipe-shaped introduction portion for introducing the developer is provided at one end of the second cylindrical member, and the plural nozzle holes are formed gradually larger as they go from the other longitudinal end to the one end. Regulating plates for regulating the amount of the developer discharged from both transverse ends of the photosensitive web are provided at both transverse ends of the first cylindrical member.
