Abstract
An image forming apparatus includes: a main assembly; an image bearing member; a transfer member cooperative with the image bearing member to form a transfer portion; a voltage source for applying a voltage to the transfer member; a heater for heating the sheet having a transferred toner image; a detector for detecting a value relating to an amount of water vapor in the main assembly; and a control unit for executing a moisture removing control for reducing an amount of water vapor produced in the main assembly, by heating the sheet by the heater on the basis of the amount of change, caused by passage of the sheet in an image forming operation, of the value detected by the detector.
