Abstract: An electrophotographic image forming apparatus including an absolute humidity derivation section which derives absolute humidity inside the apparatus, and a control section which, when the absolute humidity inside the apparatus derived by the absolute humidity derivation section is smaller than a predetermined first threshold value, sets a dither pattern density based on an original image to be smaller compared to when the absolute humidity inside the apparatus is larger than the predetermined first threshold value, and forms a latent image on a photosensitive drum.

Abstract: A print sheet creation method, including a first transfer step of forming a laminated film by transferring a first toner layer including achromatic toner and a second toner layer including chromatic toner and formed on the first toner layer to a first transfer target medium, a second transfer step of transferring the formed laminated film to a second transfer target medium from the first transfer target medium such that the first toner layer is an uppermost layer, a first fixing step of fixing the laminated film transferred to the second transfer target medium to the second transfer target medium, and a third transfer step of transferring a third toner layer which includes achromatic toner and is thicker than the first toner layer to the laminated film fixed to the second transfer target medium and having the first toner layer as the uppermost layer.

Abstract: An image forming apparatus including a binder pattern transfer section which transfers, at a first point, a binder pattern to a transfer belt moving in a predetermined direction, and a color pattern transfer section which transfers a color pattern to the transfer belt at predetermined timing, at a second point located on a lower flow side in a movement direction of the transfer belt than the first point, in which the color pattern transfer section applies electric charge to the binder pattern transferred by the binder pattern transfer section when the binder pattern passes through the second point along with a movement of the transfer belt, instead of transferring the color pattern to the transfer belt.
