PURPOSE: To form a print sheet of a structure in which no recess mark of a pressing member is formed when the print sheet is left to stand in the state that the sheet is inserted between a sheet feed roller and the member and to prevent the decrease in coloring function of a heat sensitive sheet with the substance components of a pressing member.
CONSTITUTION: A pressing roller 10 is formed of an elastic material having rubber hardness of 10° or less than that of a sheet feed roller 9. When the member 10 is energized by a linear spring 11, the member 10 side is positively elastically deformed, the deformation of the roller 9 is suppressed, and even when the sheet is left to stand for a long time in the state that the sheet is inserted between the member 10 and the roller 9, no recess mark is formed on the sheet.
