摘要： An image forming system including an image forming apparatus and a sheet feeding apparatus. The system includes: a first conveying unit conveying to the image forming apparatus a recording material; a second conveying unit conveying to an image forming unit of the image forming apparatus the recording material; a detector detecting a recording material type while the second conveying unit halts conveying the recording material; a first controller, based on detection by the detector, determining a speed for conveying the recording material to the image forming unit, and conveying the recording material at the conveying speed; and a second controller controlling recording material conveying speeds of the first conveying unit. Before the recording material reaches the second conveying unit, the second controller maintains a first conveying speed, and after the recording material reaches the second convey unit, maintains a second conveying speed determined by the first control unit.

摘要： An engine control section detects that a sheet in a cassette is exhausted during duplex image formation. If a sheet with its first surface being printed is on standby in a duplexer, an image formation timing signal is output for a first surface of a sheet not fed because of a paper-out. Subsequently, an image formation timing signal is output for a second surface of the sheet that is in the duplexer and has its first surface printed. After completing the image formation of the second surface of the sheet, the operation is halted.

摘要： The image forming apparatus includes a loop amount detection sensor, disposed between a secondary transfer part and a fixing part, for detecting a loop amount of a transfer material by detecting a reflection of light radiated on the transfer material, a density detection sensor for detecting a density of a toner image that is primarily transferred to the intermediate transfer belt with the primary transfer roller, and a loop control part for controlling the loop amount of the transfer material based on the density of the toner image that is detected by the density detection sensor and the loop amount that is detected by the loop amount detection sensor. Accordingly, the image forming apparatus attains higher accuracy in the deflection amount detection by performing the deflection amount detection at least with the dependency of the image formed on the transfer material mitigated.
