Abstract

PURPOSE:To reduce the sticking of toner on a heat fixing roller and to improve the sharpness of an image by specifying the surface roughness of the heat fixing roller and mean intervals of the ruggedness of the roller surface. CONSTITUTION:The surface of the heat fixing roller is roughened to 1-100mum ten-point mean roller surface roughness and the mean value of mean intervals Si of the ruggedness of the roller surface is specified within a range of 1-100mum. Here, the real angle of contacting between toner and the heat fixing roller is normally >=90 deg., so the angle of apparent contacting between the heat fixing roller and toner is larger and larger as the surface of the heat fixing roller is rougher and rougher. Consequently, the surface of the heat fixing roller is roughened to reduce the sticking of toner on the heat fixing roller.
