An image recording apparatus which records an image of an original document on an image receiving sheet with the use of a photosensitive recording medium, the image receiving sheet having front and rear faces differing in reflection ratio. To detect error in sheet face orientation, a sheet face sensor unit is provided upstream of a pressure developing unit which discriminates a face of the image receiving sheet. The sensor unit includes a light emitting element for emitting light toward the face of the image receiving sheet and a light receiving element for receiving light emitted from the light emitting element and reflected on the face of the image receiving sheet. A central processing unit is supplied with data representative of amounts of light emitted from the light emitting element and light received at the light receiving element, wherein the central processing unit computes a reflection ratio based on the data supplied thereto and produces a discrimination signal indicative of an error in sheet face orientation of the image receiving sheet based on the reflection ratio being computed.
