徴とする転写紙搬送装置。[Claims for Utility Model Registration] A transfer paper conveying device in which an endless belt is supported by at least two rollers including a drive roller, comprising: a first belt portion supporting the drive roller at one end; a second belt portion whose one end side is rotatably connected to the other end side of the first belt portion via a connecting shaft;
movably supported on the other end side of the second belt portion;
a driven roller around which the belt is wound; a pressure member that urges the driven roller in a direction that applies tension to the belt;
and positioning means provided at one end of the belt portion, respectively, and the applying means is arranged so that the moment generated by the pressing member acts in a direction to move the transfer paper conveying surface of the endless belt away from the photoreceptor. The line of action of the pressure member and the axis of the connection shaft are arranged to be offset from each other, and the connection shaft is arranged so that the moment due to the tension of the belt on the photoreceptor side of the belt acts in the opposite direction to the moment generated by the pressure member. A transfer paper conveying device characterized by:
