Abstract
PURPOSE: To maintain the composition of a developer stably and obtain a high quality copy by providing a developing device with a developer tray, a developer tank, a pipe, a hydrometer and a diluting water replenishing member and preventing the formation of bubbles in the tank to actuate the hydrometer normally.
CONSTITUTION: Developer 6 overflowing from developer tray 5 and returning to developer tank 7 is not simply dropped onto the surface of devloper 6 in tank 7, but introduced into developer 6 in tank 7 through developer introducing pipe 16,so bubbles are not formed in tank 7. When the specific gravity of developer 6 increases as water or a highly volatile component in developer 6 evaporates, hydrometer 10 and photosensor 11 detect the increase correctly and replenish diluting water 10 into developer 6. When the specific gravity of developer 6 returns to the original value, control circuit 12 closes control valve 13 to stop the replenishment of water 15.
