There are provided an organic electroluminescence element which is excellent in visibility and which can maintain a light emission performance with a high degree of efficiency, an image forming apparatus which is excellent in visibility and which can maintain a light emission performance with a high degree of efficiency, and a portable terminal unit which is lightweight and which has a long use life. The organic electroluminescence element incorporates at least, on a substrate, an anode for injecting holes, a luminous layer having a light emitting zone, a cathode for injecting electrons, wherein light radiated from the luminous layer is extracted through a surface opposed to the substrate, and an inverted V-like structure higher than the luminous layer is formed on at least a part of an element forming surface of the substrate.
