In a scanning type exposure apparatus for exposing an entire surface of a pattern region on a mask to a substrate by scanning the mask and the substrate with respect to a projection optical system in a predetermined direction with a speed ratio in accordance with a magnification of the projection optical system, there are provided a plurality of illumination optical systems for illuminating respective areas of the pattern region on the mask with respective light fluxes from respective light source; a plurality of projection optical systems arranged so as to correspond to the respective illumination optical systems, the projection optical systems projecting respective images of the areas illuminated by the respective illumination optical systems onto respective projection areas on the substrate; a memory device for obtaining and storing a change of shape of the substrate; a magnification changing device for changing a magnification of at least one of the projection optical systems in accordance with the change of shape of the substrate; and an imaging position changing device for changing the position of said image projected via the at least one projection optical systems in accordance with the change in magnification. An exposure apparatus for exposing a pattern of a mask onto a substrate includes an image transfer system, an imaging characteristic adjusting mechanism and an exposure system. The image transfer system projects the pattern of the mask onto the substrate while moving the mask and the substrate synchronously during the projection of the pattern onto the substrate such that portions of the pattern overlap each other. The imaging characteristic adjusting mechanism is disposed in a space between the mask and the substrate, and adjusts imaging characteristics of a portion of the image transfer system that projects the pattern onto the substrate. The exposure system exposes the pattern during the synchronous movement of the mask and the substrate by the image transfer system.
