ABSTRACT:
There is provided an image forming apparatus of the type that a toner image, which is transferred onto an intermediate transfer member, onto a sheet material, is transferred onto a sheet material, which is capable of reducing the possibility of leading end misalignment even if there is a delay in conveyance of the sheet material. An image forming device forms an image on a photosensitive member. An image carrier carries an image. A first transfer device transfers the image carried by the image carrier onto a sheet. A second transfer device transfers the image transferred onto the image carrier onto a sheet. A feeding device feeds the sheet. A conveying device conveys the sheet fed by the feeding device to the second transfer device. A controller controls the conveying device to cause the sheet to be temporarily stopped at a first location and a second location between the feeding device and the second transfer device. The controller is operable when determining that, if the sheet is caused to be temporarily stopped at the first location, the sheet cannot be conveyed to the second transfer device by the conveying device in time for timing in which the image carried by the image carrier reaches the second transfer device, for providing control to inhibit the sheet from being temporarily stopped at the first location.
