<P>PROBLEM TO BE SOLVED: To provide a light emitting device capable of providing a recorded image of high print quality when it is used as an exposure device with no complex structure as the entire device. <P>SOLUTION: The light emitting device comprises a light emitting element array 11 in which light emitting element blocks C consisting of 2×N pieces of light emitting elements T are arranged in a plurality of arrays, and (N+1) in total number of control signal transmission paths G. A control electrode 16 of a light emitting element Tn of n-th (1≤n≤2×N), from one to the other, in the array direction of the light emitting elements T in the light emitting element block C is connected to m-th (1≤m≤N+1) control signal transmission path Gm among (N+1) control signal transmission paths G, to satisfy a condition (1) m=n when 1≤n≤N, and a condition (2) m=2×N+2-n when N+1≤n≤2×N. <P>COPYRIGHT: (C)2007,JPO&INPIT |
