Abstract: A light emitting device includes a first semiconductor layer, an active layer, and a second semiconductor layer, and first and second electrodes electrically connected to the first and second semiconductor layers, respectively. The second electrode includes a reflective pad portion, a transparent electrode layer, a reflective finger portion and an electrode pad portion. The reflective pad portion is disposed in a region of an upper surface of the second semiconductor layer. The transparent electrode layer is disposed on the second semiconductor layer and has an opening encompassing the reflective pad portion such that the transparent electrode layer is not in contact with the reflective pad portion. The reflective finger portion extends from the reflective pad portion and has at least a portion thereof disposed on the transparent electrode layer. The electrode pad portion covers the reflective pad portion to be in contact with the transparent electrode layer.

Abstract: An image forming apparatus has an improved structure which avoids additional expenses associated with packing a developing unit and allows the developing unit to be stably stored. The image forming apparatus may include a body, a first developing unit accommodating portion and a second developing unit accommodating portion disposed at different positions in the body, and a developing unit which is allowed to be detachably accommodated in the first developing unit accommodating portion and the second developing unit accommodating portion. When accommodated in the first developing unit accommodating portion, the developing unit may be disposed such that it does not perform image formation. When accommodated in the second developing unit accommodating portion, the developing unit may be disposed to perform image formation.
