An optical print head in an image forming apparatus includes linearly arranged blocks and integrated circuits for driving disposed at one or both ends of the line of blocks. Each of the blocks includes a plurality of light emitting diodes. Positionally corresponding light emitting diodes in each block are connected to one of a plurality of meandering individual signal lines which are connected to the integrated circuits and each block is further connected to a corresponding common signal electrode to which power is selectively applied, thereby making possible illumination and drive of light emitting diodes in each block. The head may include a housing containing the blocks, individual signal lines and common signal electrodes and further include a flexible substrate located outside of the housing connected to and supplying power to the common signal electrodes. |
