ABSTRACT:
The present invention has an object to provide transfer paper for electrophotography which is excellent in paper-feed conveyability and image quality. The invention provides transfer paper for electrophotography having coated layers on both sides of a substrate material, comprising a first coated layer, containing a print seam, provided on at least one side thereof and a second coated layer provided on said first coated layer and having a print seam different from that of the first coated layer; wherein the total weight of the transfer paper for electrophotography is within a range from 60 to 130 g/m2. The manufacturing method of the transfer paper for electrophotography according to the present invention comprises a first coating step for coating a first coated layer having a print seam on at least one of the sides; a drying step for drying the first coated layer formed in the first coating step; and a second coating step for coating a second coated layer having a print seam different from the first print seam, over the dried first coated layer; wherein the transfer paper for electrophotography has a total weight within a range of from 60 to 130 g/m2.
