Image forming apparatus and storage medium

A non-transitory storage medium storing a computer readable program for a computer in an image forming apparatus including:

• an image former that includes an intermediate transferer to which a toner image is primarily transferred to perform primary transfer, and a secondary transferer to which a transfer bias for secondarily transferring the toner image on the intermediate transferer to a continuous recording medium is applied;
• and a conveyor that is arranged on a downstream side of the image former in a conveyance direction of the continuous recording medium and conveys the continuous recording medium, the program causing the computer to perform controlling that is controlling a speed of the intermediate transferer and a speed of the continuous recording medium conveyed by the conveyor, wherein
• the program causes the computer to control a timing at which the transfer bias is applied to the secondary transferer, perform control such that the speed of the continuous recording medium conveyed by the conveyor is higher than the speed of the intermediate transferer, and start application of the transfer bias to the secondary transferer after the secondary transferer is pressed against the intermediate transferer and before the primary transfer is started.
