If an edge of a sheet metal of a image forming apparatus damages an electric
cable,
the image signal is distorted and no correct image is formed since the damage causes
feeding failure and signal deterioration. This is remarkable in the conventional
digital electrophotographic apparatus, since the drive signal to drive a laser
or a light emitting diode (LED) for exposing the photosensitive body becomes higher
in frequency as a resolution and speed are increased and tends to generate the
electric noise. In order to prevent damage of an electric cable by a metal frame,
an apparatus having a holder for holding a feed cable is provided.
