A coreless thermal transfer recording web rollis formed by rolling a thermal transfer recording weba in a roll. An inner end partof the thermal transfer recording weba of the thermal transfer recording web rollhas a taba formed at a substantially middle of the inner end partand sticking partsb formed on the opposite sides of the taba, respectively. Pseudoadhesive double-coated tapesare attached to the sticking partsb, respectively. The pseudoadhesive double-coated tapes become tack-free after the sticking partsb have been separated from the innermost layer of the thermal transfer recording weba of the thermal transfer recording web roll

A thermal transfer printer includes a thermal transfer recording web roll having a bore and obtained by rolling a thermal transfer web. The segment of the thermal transfer recording web forming the innermost layer of the thermal transfer recording web roll is fixed to a part of a segment of the same forming the second innermost layer of the thermal transfer recording web roll. A holding device is inserted in the bore of the thermal transfer recording web roll to hold the thermal transfer recording web roll. The thermal transfer recording web roll and the holding device rotate in a unit to feed the thermal transfer recording web to a thermal transfer recording unit that forms images on the thermal transfer recording web. The thermal transfer recording web roll can be prepared at a low cost without requiring much time and effort.
