The only reference on google for rtdrvmon is rtdrvmon.exe, which is related to a Lexmark printer/scanner/copier.
I don't expect Windows or Lexmark to put a component needed for a printer to work in the recycle bin. And, in fact, I don't expect Windows to put it there if you uninstall the driver for some reason.
Either you deleted it yourself; then it's safe to delete only if your Lexmark copier still completely works. Otherwise put it back.
Or it's some malware which hides itself in the recycle bin, as some smartly do. Better run the anti-parasite suite then before deleting it manually yourself.
Hope this helps.
