Image forming method

摘要

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.

1. An image forming method that employs an electrophotographic system to form a stacked toner image which has a color toner image of a color toner and a clear toner image of a clear toner superimposed one on another in that order on an image support, and then collectively fixes the resulting stacked toner image on the image support, the image forming method comprising:
forming the color toner image 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 forming the clear toner image in accordance with a clear image signal obtained through contone processing on the manuscript image data, wherein the clear image signal for forming the clear toner image is controlled so that according to an 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 per unit area, the more an amount of the clear toner becomes, and wherein the clear toner has a volume-based median diameter that is smaller than a volume-based median diameter of the color toner.
