ABSTRACT:
The present invention intends to reduce the deterioration of the image quality due to the color deviation in an image forming apparatus wherein color toner images formed on an image bearing member are successively transferred onto a transfer sheet superimposedly to form a color image. In the apparatus wherein the transfer sheet conveying means supports the transfer sheet only by an electrostatic attraction force, since the adhesion condition of the transfer sheet on the transfer sheet conveying means differs between the first color and the other colors, the color toner image firstly transferred to the transfer sheet is an yellow color toner image which is a most unnoticeable color.
