Abstract: A manufacturing method for a silicone rubber molded body that is to be used in an electrophotographic image forming apparatus includes a heating process of a precursor of a silicone rubber molded body. The heating process includes heating the precursor of a silicone rubber molded body and externally introducing an environmental gas and discharging the environmental gas to outside, to reduce an amount of a low molecular weight compound remaining in the precursor of a silicone rubber molded body.

Abstract: An image forming method which is capable of preventing occurrence of moire and forming images having sufficient color saturation and a sufficient gloss is provided. The color toner image is formed in accordance with a color image signal obtained through screen processing using a screen pattern having a screen line count of 50 to 270 lpi on manuscript image data, and the clear toner image is formed in accordance with a clear image signal obtained through contone processing on the manuscript image data. The clear image signal is controlled so that, according to the amount of the color toner per unit area of the stacked toner image obtained by the color toner image being superimposed with the clear toner image, the less the amount of the color toner, the more the amount of the clear toner becomes.
