Abstract: There is provided an image forming apparatus that includes a color image former that forms a color image with a plurality of process color toners, a spot color image former that forms a spot color image with a spot color toner, a transfer unit that transfers the formed color image and the formed spot color image onto a recording material, a fixing unit that fixes the transferred color image and the transferred spot color image onto the recording material, and a hardware processor that selects a first mode or a second mode depending on whether or not a type of the recording material and an amount of toner to be attached onto the recording material satisfy a predetermined condition. The number of times of image transfer and fixation onto an identical surface of the recording material is two or more predetermined times in the first mode. The number of times of image transfer and fixation onto an identical surface of the recording material is less than the predetermined times in the second mode. When images are formed on both surfaces of the recording material, the predetermined condition differs between a first surface and a second surface of the recording material.

Abstract: An image forming apparatus provided with a transfer device includes a separator, a post-transfer-residual-quantity acquirer, and a controller. The transfer device transfers an image formed on an image carrier to a transfer medium. The separator is arranged at downstream side from a transfer device in a conveying direction, is provided with a separation claw which contacts with the image carrier and separates the transfer medium from the image carrier, and performs contact/separate operation of the separation claw with/from the image carrier. The post-transfer-residual-quantity acquirer acquires post-transfer residual quantity in a region determined on a basis of a position of the separation claw in an axial direction of the image carrier. The controller controls the contact/separate operation of the separation claw with/from the image carrier on a basis of the post-transfer residual quantity acquired by the post-transfer-residual-quantity acquirer.
