摘要： An image forming apparatus (100) including at least one latent image carrier (2), an image forming unit to form a toner image on the at least one latent image carrier (2) based on image data, a transfer body (8) onto which the toner image formed on the at least one latent image carrier (2) is transferred in one or more valid image ranges, a non-image range determiner (31) to determine a non-image range on a surface of the transfer body (8) onto which the toner image is not transferred, a surface detector (23) to detect the surface of the transfer body (8) in the non-image range, and a toner determiner (33) to determine whether or not toner is present in the non-image range based on a result detected by the surface detector (23).
