。 a toner supply means having a supply pipe line for supplying liquid toner in a toner tank to a developing section; a surplus toner collecting section for collecting surplus toner after development in the developing section; a toner discharging means including a discharge pipe for discharging excess toner to the toner tank; reed switches disposed at two locations near the upper end and the lower end of the surplus toner collecting section; and a liquid level detecting means for detecting the liquid level of excess toner in the surplus toner collecting section, which is comprised of a float magnet disposed so as to be movable up and down, and the reed switch near the upper end is activated by the operation of the liquid level detecting means. A liquid developing device characterized in that when in an ON state, it is possible to detect occurrence of toner clogging in the toner discharge pipe, and further, when a reed switch near the lower end is in an ON state, it is possible to detect a decrease in toner in the toner tank. .
