A photosensitive member unit of a recording apparatus including a photosensitive member in the form of an endless belt supported by a plurality of rollers which is movable for recording information from a document on a transfer-printing sheet. The photosensitive member unit further includes a tension roller displaceable with respect to one of the plurality of rollers, and tensioning means operative to move the tension roller when the photosensitive member unit is mounted to a main body of the recording apparatus to thereby tension the photosensitive member in the form of an endless belt. The photosensitive member unit is removably mountable to the recording apparatus, and when it is stored in reserve without being mounted to a recording apparatus, tension is automatically removed from the photosensitive member.
