Foam rollers really simplify the process. They make it easier to paint the door without drip marks, and they leave a smooth finish. Using both tools together will bring about the best results in painting your interior door.
You want to use a mini foam roller to paint an interior door. The high density foam will prevent roller marks. If your door is flat, you can use a full sized roller. If it has details, use a mini roller.
If you are going to paint a plain, flat door, use a foam roller to roll on the paint and use an angled brush to paint the sides. You want to make sure you leave no roller lap marks. To remove any lap marks, roll a lightly-loaded roller over the wet coat of paint to smooth.
Walls, Wood, and Metal - Small 1/4″ nap roller covers or foam rollers will produce the smoothest finish. Light to Medium Textured Surfaces - Microfiber rollers are best. Smooth Surfaces - Use a white woven short nap roller for an ultra fine finish.
The best way to paint your door is by using both a paintbrush and a foam roller. You should begin by brushing a light coat of paint on the door. Because the brush can leave drips or runs, it is best to do this first, before the rest of the door is painted.

“Painting a front door is best done with a brush. This is because most front doors have wood and/or glass panels and a roller would not be able to paint in the panels the same way that a brush would to give full coverage.”

The standard method for painting residential walls is usually to "cut in" around baseboards and wood trim with a small paintbrush, then paint the "field" of the walls using a paint roller. But there are instances where painting the entire wall surface with a brush is the better strategy.
Paint rollers have a metal roller attached to a frame that is designed to rotate, so if the paint roller is sliding instead of rolling, it's a sign that you have overloaded the roller with paint. This will cause the roller to slide and smear, instead of smoothly rolling.
