Exposure device and image forming apparatus

An image forming apparatus comprising:

• a photoconductor on which a latent image is to be formed by exposure to light;
• and
• an exposure device that exposes the photoconductor to light,
• the exposure device including
• a plurality of light emitting elements that emit light which an exposure target member is exposed to,
• a driving circuit that performs at least one of a first drive operation and a second drive operation, the first drive operation being an operation of receiving a plurality of image signals, which have been supplied, corresponding to the plurality of light emitting elements and of individually driving, for use in exposure to light, the plurality of light emitting elements in accordance with the plurality of image signals, the second drive operation being an operation of receiving supplied light-amount adjustment control signals used to control amounts of light and of individually driving, for use in adjustment of the amounts of light, the plurality of light emitting elements in accordance with the light-amount adjustment control signals,
• an image-signal cable in which a plurality of core wires through which the plurality of image signals are transmitted are arranged at a first pitch and which is formed so as to have a sheet shape,
• an image-signal connector that has a plurality of terminals connected to the plurality of core wires of the image-signal cable, and that relays the plurality of image signals, which have been transmitted through the image-signal cable, to the driving circuit,
• a plurality of power cables through which power is transmitted,
• a power connector that has a plurality of terminals which are arranged at a pitch substantially wider than the first pitch, and that relays power, which has been transmitted through the plurality of power cables, to the driving circuit, each of the plurality of terminals of the power connector being connected to a corresponding one of core wires of the plurality of power cables,
• a plurality of adjustment-control-signal cables through which the light-amount adjustment control signals are transmitted, and
• an adjustment-control-signal connector that has a plurality of terminals which are arranged at a pitch substantially wider than the first pitch, and that relays the light-amount adjustment control signals, which have been transmitted through the plurality of adjustment-control-signal cables, to the driving circuit, each of the plurality of terminals of the adjustment-control-signal connector being connected to a corresponding one of core wires of the plurality of adjustment-control-signal cables.
