Potty Training

So we've started potty training! He poops fine in the potty and does every day now. It's great! My question is how do I get him to pee more on the potty? He goes sometimes, kinda just dribbles here and there, but mainly pees in his diaper. We spend about 30 mins on the potty a little while after he drinks. I don't want to spend an eternity in there every time. He never pees very much and then as soon as I put his diaper on, he pees. How do I combat this?

In short, he pees a little in the potty, a lot in his diaper MINUTES after I take him off the toilet. -_-
