Abstract:
A fixing device includes a heating body, a pressuring body, a heating source, a guiding part, a temperature sensing part and a charging part. The heating source supplies the heating body heat used for heating the medium. The guiding part guides the medium to a nip between the heating body and the pressuring body, at an upstream side from the nip in a conveying direction of the medium. The temperature sensing part senses a temperature of the heating body. The charging part electrically discharges to electrically charge the heating body with the same polarity as toner, at an opposite side to the guiding part across the temperature sensing part. The charging part includes a discharging electrode electrically discharging toward the heating body facing to the discharging electrode and an enclosure wall supporting the discharging electrode, enclosing the discharging electrode and producing an electric field in cooperation with the discharging electrode.

Claim (Index 1):
A fixing device comprising:\n a heating body formed in a tube-like shape and, while rotating, heating a medium conveyed after a toner image is formed on the medium; a pressuring body formed in a tube-like shape and, while rotating, forming a nip in cooperation with the heating body and pressuring the medium by sandwiching the medium in cooperation with the heating body at the nip; a heating source supplying the heating body heat used when the heating body heats the medium; a guiding part positioned at an upstream side in a conveying direction of the medium with respect to the nip and guiding the medium being conveyed to the nip; a temperature sensing part positioned to face to the heating body and sensing a temperature of the heating body; and a charging part positioned at an opposite side to the guiding part across the temperature sensing part, being configured as a corotron type charging part electrically discharging to electrically charge the heating body with the same polarity as polarity of toner, and including: a discharging electrode electrically discharging toward the heating body facing to the discharging electrode; and an enclosure wall supporting the discharging electrode, enclosing the discharging electrode and producing an electric field in cooperation with the discharging electrode.
