If the charge roller is new and/or clean and the electric contacts are clean and making contact, I would then look at the developer mag roller. Make sure it is clean, often times they get black from toner build up. Clean the mag roller with a brass brush.

Definitely looks like drum cleaning issue. You may have a low spot (dent) in the pcu. Replace the pcu and cleaning blade.

if you accidentally touch the charge roller try to clean it thoroughly. You can use plain water.

Dude, that looks like all PCU. As mentioned, make sure your spring terminals are contacting for the charge roller, although the rotation appears to be a drum problem. Don't blow it out, vac it out and see if you might not have goop in the pcu auger, or a failed blade as TB suggested. If your drum is dented, you will see it right off the bat.
