Image forming apparatus and fixing device

摘要

An image forming apparatus includes a photosensitive member, a fixing device, and a fan. The fixing device includes a heating member, a pressing member, and a frame. The heating member includes a heater configured to generate heat, a cylindrical member storing the heater therein, and first and second support terminals disposed at first and second ends of the heater, respectively, in a longitudinal direction of the heater, the first and second support terminals supporting the heater. The frame is made of resin, and includes a first support terminal supporting portion supporting the first support terminal of the heater and a second support terminal supporting portion supporting the second support terminal of the heater. The frame further includes a duct portion disposed proximate to the first support terminal supporting portion, the duct portion through which air flows to the fan.
