摘要： An image forming apparatus includes a recording material transporting path that extends in a direction from bottom to top of a body of the image forming apparatus and transports a recording material, a fixing device provided on the recording material transporting path, which includes a rotatable heating member that has an internal heat source and a rotatable pressure member that forms a nip area with the heating member by being located in contact with and pressed against the heating member, to nip the recording material for carrying out a fixing process, and an ejection guide member that guides a recording material ejected from the nip area to the outside of the image forming apparatus. The ejection guide member has a guide surface formed to intersect a tangent line of the heating member at the most downstream point of the nip area, and the guide surface intersects the tangent line at an obtuse angle.
