GeoServer doesn't produce maps in image/GEOTIFF format.

You are confusing the input and output formats of the WMS. GeoServer
is already aware that your image is a GeoTiff from the way you added
the layer to it. OpenLayers meanwhile is expecting that the map be
sent using png, gif or jpeg - for best results leave the format option
out of the request as OpenLayers will fill it in with whatever it
wants.
