Patent ID: 7244488

Claim:
An electrophotographic transfer paper having a substrate and a thermoplastic foamed resin layer which is provided on at least one surface of the substrate and has pores, wherein the temperature at which the viscosity of the thermoplastic foamed resin layer becomes 1×10 4 Pa·s ranges from 60° C. to 100° C. and a gradient R of a viscosity-temperature curve of the thermoplastic foamed resin layer defined by the following Equation (1) ranges from 0.02 to 0.10: R={Log(η t )−Log(η t+20 )}/20 (1) where η t indicates 1×10 4 Pa·s and η t+20 indicates the viscosity (Pa·s) of the thermoplastic foamed resin layer at a temperature higher by 20° C. than the temperature showing the viscosity η t .
