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.

摘要： An image forming apparatus includes a recording material transporting path that extends in a direction from below upward and that transports a recording material, a fixing device provided on the way of the recording material transporting path, the fixing device having a rotatable heating member that has a heating source provided inside thereof and a rotatable pressure member that forms a fixing nip in pressure contact with the heating member, and a detaching member that contacts the heating member in the vicinity at a downstream side of the of the fixing nip in the rotation direction of the heating member and detaches the recording material from the heating member. The detachment member has a detachment guide surface extending from a contact point with the heating member, and a tilt of the detachment guide surface toward the pressure member side in relation with a vertical line including the contact point is not more than 2.5°.
