Abstract
An image forming method for forming an image by transferring toner image formed on a photoconductive element to a paper sheet or similar recording medium. Variable factors affecting image transfer, paper separation and paper transport characteristics are classified. An image transfer state, a paper separation state and a paper transport state are each estimated as a combination of membership functions of the variable factors to determine an image transfer condition, a paper separation condition, a paper transport condition and auxiliary conditions such that control is executed on the basis of the determined conditions.
Claims7
In an image forming method forming an image by transferring a toner image formed on a photoconductive element to a recording medium, variable factors associated with image transfer, paper separation and paper transport characteristics are classified into one of short-term, medium-term and long-term factors, and an image transfer state, a paper separation state and a paper transport state are each estimated as a combination of membership functions of said variable factors to thereby determine an image transfer condition, a paper separation condition and a paper transport condition, whereby control is effected on the basis of said determined conditions at predetermined timings which correspond to said short-term, medium-term and long-term factors.
