INKJET PRINTING APPARATUS

摘要

Provided is an inkjet printing apparatus including a first transport roller disposed on a transport path transporting a long print medium, a second transport roller disposed on the transport path downstream of the first transport roller, a print medium holder disposed downstream of the second transport roller, and a recording unit discharging ink droplets to a printing area of the print medium, and performing recording operation, the print medium being transported on the transport path. The first transport roller has a first winding angle upon contact to the print medium. The second transport roller has a second winding angle upon contact to the print medium. The first winding angle is larger than the second winding angle. The first winding angle is equal to or more than 75 degrees. The sum of the first and second winding angles is equal to or more than 80 degrees.
