摘要： An image forming apparatus has a structure in which a toner image formed in an electrophotographic process is transferred from an intermediate transfer belt to a member to be transferred. The apparatus includes a secondary transfer roller that becomes a pressure contact state with respect to the intermediate transfer belt to make it perform a transfer process and can move between the pressure contact state and a separated state, and a press and separation driving device for driving the secondary transfer roller to become the pressure contact state and the separated state. The pressure contact state or the separated state of the secondary transfer roller is detected in accordance with a variation of an output of an IDC sensor for detecting a state of a bare surface of the intermediate transfer belt.

摘要： An electrophotographic image forming apparatus includes a developing device including a developer reservoir for accommodating a mixed developer. The mixed developer includes a plurality of types of toner having a generally identical hue and different reflection densities. The apparatus also includes a replenishment device having a plurality of toner containers each accommodating one of the plurality of types of toner for replenishing the plurality of types of toner to the developer reservoir; a first detector for detecting whether each of the toner containers is completely empty of toner; and a second detector for detecting whether the developer reservoir is nearly or completely empty of mixed developer. A controller controls the replenishment device and allows or prohibits a printing operation based on the detection result of the first and the second detectors.
