An image forming apparatus includes: an image bearing member; a toner image forming unit; a belt member; a transfer member; a transfer voltage source for generating a voltage applied to the transfer member; an obtaining portion for obtaining information on an electric resistance of the belt member; a detecting member for optically detecting a test toner image formed on the image bearing member and transferred on the belt member; and an executing portion for executing, on the basis of a detection result of the test toner image by the detecting member, an adjusting operation for adjusting an image forming condition of the toner image forming unit. The executing portion sets, on the basis of the information, a voltage applied to the transfer member when the test toner image is transferred onto the belt member in the adjusting operation.
