check drum unit also, especially the primary roller, seems like contact is bad

I have changed the Drum unit and Developing unit but the same problem existing

hmmm , check electric contacts and the high voltage .. check fixing unit too .it seems something periodic

ok, you changed drum and developing unit, so we can assume, that they are ok. On your picture one can see clearly, that the marks are in equal distance, so it must be something rotating. I would go for the transfer roller and its contacs as next step. even if it seems unlogical that a transfer roller can cause such an image.
