Image forming apparatus

An image forming apparatus comprising:

• a plurality of light-emitting elements, each light-emitting element receiving a driving current from a power supply and converting the current into a beam;
• a plurality of driving elements, each driving element being electrically connected between the power supply and each light-emitting element and controlling the driving current for each light-emitting element based on an image signal;
• and
• a photoconductor on which the beams from the plurality of light-emitting elements form an image by scanning,
• wherein each light-emitting element is positioned adjacent to each driving element such that a power leakage factor floating between the light-emitting element and the driving element is reduced, whereby an intensity of the beam is substantially equivalent to the image signal in waveform,
• wherein each light-emitting element comprises a laser diode and the power supply comprises a d.c. power supply, an anode of the laser diode being connected to a positive electrode of the power supply, a cathode of the laser diode being connected to a negative electrode of the power supply through the driving element, and
• wherein each laser diode is mounted in a metallic package, the anode of the laser diode being connected to the metallic package.
