A transfer and fixing device as means for heating a recording medium prior
to transfer and fixing, without risk of fire, superior in energy
efficiency, and able to stably heat irrespective of the thickness of the
recording medium; and an imaging forming apparatus comprising such a
transfer and fixing device comprising: a transfer and fixing member by
which an image is transferred; a pressurizing member that forms a nip by
pressure contact with the transfer and fixing member and pressurizes and
fixes the image on the recording medium that passes through the
aforementioned nip; a radiant heat source that is arranged on the
upstream side of the nip in the direction of transport of the recording
medium; and a thermoconductive member that is heated by the radiant heat
source and heats the recording medium when in contact, wherein a radiant
heat region is provided, between the nip and the thermoconductive member,
where the recording medium is heated by radiant heat from the radiant
heat source.
