Abstract:
1. An image forming method in which an electrostatic latent image formed on a surface of a photoreceptor is developed into a developer image with a developer, and in which a printing paper sent out from a paper feeding section and transported on a transport belt is brought into contact with the surface of the photoreceptor so as to transfer the developer image onto the printing paper, said method comprising the steps of: (i) detecting a height of a printing paper bundle loaded in the paper feeding section, both at a front end portion and a rear end portion with respect to a direction of ejection of the printing paper from the paper feeding section; (ii) determining a current placement direction of the printing paper bundle from a result of detection in the step (i), the current placement direction indicative of whether a projection generated in one direction on the printing paper as a result of cutting the printing paper in a printing paper manufacturing process is present on which the front end portion and the rear end portion of the printing paper bundle with respect to the direction of ejection; and (iii) comparing the current placement direction with a proper placement direction, which is a direction set for the printing paper bundle in the paper feeding section so that the printing paper is transported with the projection not facing a surface of the transport belt at a leading edge of the printing paper being transported, and when the current placement direction and the proper placement direction do not match, giving a warning.
