摘要：
The present invention provides a fixing device for fixing an unfixed image onto a recording sheet by applying heat and pressure to the unfixed image while the recording sheet having the unfixed image formed thereon is passing through a fixing nip, the fixing nip being formed by pressing a pressurizing roller against a heat generation belt, wherein the heat generation belt rotates around a rotational axis and includes a resistive heat layer extending in a rotational axis direction thereof, the resistive heat layer configured to generate heat when electricity is supplied thereto and having a plurality of holes provided therein, and the holes are distributed unevenly in the resistive heat layer such that electrical resistivity of the resistive heat layer varies in the rotational axis direction.
