Thanks for the pictures. To me it looks like acceptable ghosting and about what I expect from the 505's generation of e-ink (I have one too). Like I said, the ghosting can be more or less pronounced depending on the reader's/ambient temperature and on how it was configured before it left the factory - the e-Ink controller has waveform data that is matched to the display material. Also there is a temperature compensation that is unique for every display, so try letting your reader "warm up" to room temperature and see how you get on.
For some more information about this waveform and ghosting stuff (although it is geared towards irex's iLiad) see
this page)
If you feel the ghosting is really too much (try reading a couple of books) you could contact Sony again.
Here's a bit from the Sony reader

Has Sony experienced any issues with “ghosting”?
Please refer to the FAQs on the E Ink web site (www.eink.com) to understand the causes and effects of “after image” (ghosting). While our engineering objective is to minimize the after image effect through clever control waveform design, after image is an inherent characteristic of the E Ink technology and is not a sign of a defective or degraded display.
