ABSTRACT:
An image forming apparatus includes an image forming section and a toner cartridge which is loadable into the image forming section. The toner cartridge includes a seal member which is bonded to a peripheral edge of a toner discharging port by an electro-releasing adhesive, of which adhesive force decreases when a current is applied thereto. The image forming section includes a first electrode and a second electrode that contact the peripheral edge of the toner discharging port and the seal member, respectively, when the toner cartridge is loaded into the image forming section. When a current is applied to the electro-releasing adhesive via the first and second electrodes, the adhesive force of the electro-releasing adhesive decreases, whereby the seal member is released from the toner discharging port.
