Patent ID: 11454917

Abstract:
An image forming apparatus includes an image bearer, a protectant applicator, a heating device, and a protectant biasing member. The protectant applicator applies protectant to the image bearer. The heating device includes a heater including a base, a heat generator, an electrode, and a conductor coupling the heat generator to the electrode. The heater has a first position and a second position having a higher temperature than the first position. These are symmetrical to each other with respect to a longitudinal center of a heat generation area of the heater. The protectant biasing member biases the protectant to the protectant applicator with a first biasing force at a position closer to the first position than to the second position and with a second biasing force larger than the first biasing force at a position closer to the second position than to the first, and the protectant contacts the protectant applicator.
