A laser printer includes a photoreceptor drum, a transfer roller contacting the photoreceptor drum, a transfer roller frame holding the transfer roller, an outer frame holding the transfer roller frame, a diselectrification brush fixed to the transfer roller frame, and a spring at least having a surface formed of conductive material for biasing the transfer roller toward the photoreceptor drum. The spring is formed of a single member and has a first extension contacting the diselectrification brush and a second extension contacting the outer frame.
