1992 Toyota Corolla How to replace outside door handle

I took out the inside door handle but I can't figure out how to remove the window handle roller. I try to fry it with screw driver but it won't come out. I'm afraid that I will break it. I wonder if the handle roller is just an snap on or with screw. I already un-snap the door panel. What is left is this handle roller. I broke my outside door handle and I want to replace it.
