Patent ID: 6876820

Claim:
An image forming apparatus comprising: plural image carriers that carry toner images formed by an image forming process in operation thereof and are disposed along a sheet transport direction; a transfer carrier for transporting a sheet recording medium attracting it in the sheet transport direction to transfer said toner images carried on said plural image carriers onto said sheet recording medium; a transfer voltage applying section for applying a transfer voltage to said sheet recording medium carried on said transfer carrier; a fixing device for fixing a toner image on said sheet recording medium transported by said transfer carrier and is installed so as to be capable of moving toward outside of a side surface of the body of said image forming apparatus; and a jam processing control section for detecting occurrence of a jam on said sheet recording medium during said image forming process to process said sheet recording medium in said jam, wherein said jam processing control section, when detecting occurrence of said jam, ceases transportation of said sheet recording medium in said jam by said transfer carrier as a first stage to make it possible to remove said sheet recording medium in said jam, and, if a second sheet recording medium in transit when said jam occurs is detected by said transfer carrier, advances to a second stage and restarts transportation of said second sheet recording medium in transit using said transfer carrier so that a transport distance thereof corresponds to a printing ratio of said image formed on said second sheet recording medium.
