Abstract

PURPOSE: To realize a circulating use of cohered developer by securing such constitution in that the double-current developing solution is returned to the part near the developing solution sent-out pump in the developing solution storing container and thus securing the fractionization and redispersion of the coagulated developer contained in the double-current developing solution.
CONSTITUTION: The opening 56 is provided at the cover 55 of the devellping solution container 51 corresponding to the part near the developing solution send-out pump 52 in the container 51, and then the cover surface within the frame 60 is tilted toward the opening 56. Thus the double-current developer dropped onto the cover surface within the frame 60 is all gathered at the opening 56 to be sent back to the area near the pump 52. The coagulated toner in the double-current developer developer is fractionized and dispersed in an extremely effective way for the second circulating use by the overall action of the strong turbulent flow of the developing solution caused at the area near the pump 52, the collision of the cohered toner against the rotary agitating blade 63 attached to the rotary shaft 62 of the pump 52 and the toner striking action to the pump filter 64 respectively.
