Hello, This is a common problem with the Konica 7155/65, 7255 and 7272. No real fix is out there I have some that do run cleaner than others and I have heard paper dust may cause it to be worse......Always clean the dust brushes when servicing and make sure toner suction filter is vacuumed out every call.

If your developer unit has a 700-900K count, replace it. Here's something new that seems to be working: set the dev. bias number (36 mode, high voltage manual adjustments) to "150" (range allowed is "0" to "200"). Got this tip from a good tech on another forum.
