Image forming apparatus

An image forming apparatus can form a high-quality image without a toner image being rubbed with and transferred onto a sheet. The apparatus includes: an image carrier that transfers a toner image onto a sheet; a transport roller disposed upstream of a transfer position where the toner image is transferred onto the sheet from the image carrier in a sheet transport direction, and closest to the transfer position among rollers transporting the sheet; a guide section arranged between the transfer position and the transport roller, and changing over between a first guide state where the transported sheet is guided to contact a surface of the image carrier with a first contact area, and a second guide state where the transported sheet is guided to contact the surface of the image carrier with a second contact area smaller than the first contact area; and a guide control section allows the guide section to guide the transported sheet in the second guide state when the rear edge of the transported sheet passes through the transport roller.
