Disclosed is an image forming apparatus including: an image former that includes an intermediate transferer, 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; a conveyor that is arranged on a downstream side of the image former and conveys the continuous recording medium; and a hardware processor that controls a speed of the intermediate transferer and a speed of the continuous recording medium conveyed by the conveyor. The hardware processor controls a timing at which the transfer bias is applied to the secondary transferer, performs control such that the speed of the continuous recording medium is higher than the speed of the intermediate transferer, and starts application of the transfer bias after the secondary transferer is pressed against the intermediate transferer and before the primary transfer is started.

Image forming apparatus and storage medium

A belt slippage correcting device includes: a belt moving part that moves a belt in a width direction of the belt; a slippage detector that detects a slippage of the belt in the width direction; a hardware processor that controls a movement of the belt caused by the belt moving part based on the slippage of the belt detected by the slippage detector; and an acquisitor that acquires paper sheet conveying property, wherein the hardware processor controls an amount of movement of the belt caused by the belt moving part based on the paper sheet conveying property acquired by the acquisitor.

Belt slippage correcting device and image forming apparatus

A fixing device and An image forming apparatus include: a first pressure roller having an elastic layer in a surface layer section; a fixing belt wound on the elastic layer of the first pressure roller; a second pressure roller that presses the elastic layer of the first pressure roller via the fixing belt, the second pressure roller forming a fixing nip portion between the fixing belt and the second pressure roller; and a guide member that guides the fixing belt in such a manner as to separate the fixing belt from a protruding portion of the elastic layer, the protruding portion being formed on an entrance side of the fixing nip portion in a sheet conveying direction.
