Abstract: Disclosed is a toner residual quantity detecting apparatus for detecting a residual quantity of toners in a developing unit. This toner residual quantity detecting apparatus has a temperature sensor, provided in the bottom of the developing unit, for generating an output proportional to a detected temperature and a detecting circuit for detecting the toner residual quantity from the output of the temperature sensor. This temperature sensor detects a difference between temperatures when covered with the toners and when not covered with the toners, thereby detecting the toner residual quantity.

Abstract: An electrophotographic image forming apparatus includes an electrostatic latent image carrying body, an electric charger for uniformly electrifying the carrying body, an optical exposure unit to form an electrostatic latent image on the carrying body, a developer for developing the electrostatic latent image to form a toner image on the carrying body, a transfer unit for transferring the toner image from the carrying body onto a printing sheet, a fixing unit for fixing the toner image to the printing sheet, a cleaner for cleaning to remove residual toner from the carrying body and a toner returning mechanism for returning the residual toner removed by the cleaner to the developer.
