An image forming apparatus includes: a plurality of photoreceptors; a plurality of exposure heads provided so as to correspond to the plurality of photoreceptors, respectively, each of the plurality of exposure heads including a plurality of light emitting units configured to emit light for exposing the corresponding photoreceptor, the plurality of light emitting units being arranged along a rotation axis line of the corresponding photoreceptor; and a generation unit configured to generate a line synchronization signal for each of the plurality of exposure heads to control a light emission timing in a rotating direction of the corresponding photoreceptor, the generation unit being configured to adjust a cycle of the line synchronization signal in accordance with each of the plurality of exposure heads.

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.

An image forming apparatus includes an image carrier, a charging device, an exposure device, a developing device, a transfer portion, a cleaning blade, and a control section. The control section detects a charging current amount of the image carrier and, when an integrated current amount obtained by integrating values of the charging current amount in a prescribed length of time is lower than a prescribed threshold value, performs an aging process in which the image carrier is driven to rotate in a charged state.
