An image forming apparatus satisfying relations Xd>distance Xe between image exposure position and potential detecting member>2xtauxPSxVc/VmuxMc/Mmu and 0<distance Xt between image exposure position and temperature detecting member<50xtauxPSxVc/VmuxMc/Mmu (tau: time constant (sec) in a hole mobility measurement by TF method; PS: process speed (mm/sec); Vc: latent image contrast (V) necessary for image formation; Mc: thickness (cm) of charge transport layer in a photosensitive member; Vmu: bias (V) applied to a specimen in a hole mobility measurement by TF method; Mmu: thickness (cm) of a charge transport layer of a specimen employed in a hole mobility measurement by TF method; and Xd: distance (mm) of an image exposure portion and a developing device in a position opposed to the photosensitive member.
