Azazel is unlocked by making three Deals with the Devil in a single run.

To get a Deal with the Devil you need to try and fill certain criteria to make the room appear after defeating the boss on any given floor. Here is a list of criteria and the probability increase they give for finding a room.

Take no Red Heart damage for the floor - +99% (You can take Spirit Heart damage)
Take no Red Heart damage against the boss - +35%
Holding the Pentagram - +20% (+10% with Afterbirth)
Holding a second Pentagram - +10% (+5% with Afterbirth)
Holding Black Candle - +30% (+15% with Afterbirth)
Holding Book of Revelations - +35% (+17.5% with Afterbirth)
Killing a Judgement Beggar with a bomb - +35%
Blowing up Shopkeeper - +10%
Holding Book of Belial - +2500% (+12.5% with Afterbirth)
Holding Goat Head - Guarantees Devil Room on every possible floor

Finally if you have visited a Devil Room in the past the following multipliers will be applied to your current % chance of finding another.

Devil Room found within last two floors - x0.5
Devil Room found more than two floors ago - x0.25

This means that if you have found one within the last two floors your chances of finding another for the two floors following are cut in half, any floors beyond that it goes down by 25%

To complete a deal you must either exchange Red Heart containers for items or if you have no Red Hearts you can exchange Soul/Devil Hearts instead. Items will cost between 1 and 3 Red Heart containers, if you have no Red Hearts all items will cost 3 Soul/Devil Hearts.

Upon completing your third deal Azazel will unlock.
