Abstract: A heating roller for a wet ink-based image forming apparatus includes a roller having a contact surface to contact a print medium having wet ink deposited thereon by wet ink-based image forming apparatus. The heating roller conductively heats the print medium and dries and flattens the print medium. The heating roller includes a heating element embedded along the roller. The heating element rotates with the roller as the roller rotates. The heating element generates and conducts heat to the contact surface so as to conductively heat the print medium through the contact surface when the contact surface contacts the print medium.
