Refer to photos. A section of the chain is rotated outwards and the rest is perfectly straight. This causes the chain to derail from the jockey wheel in the rear derailleur.

You have a bent link somewhere. Look from the back of the bike to find the culprit. Two pairs of pliers on the link you can bend it back straight.
Chains need to be replaced regularly. Break the chain apart and you should see the damaged pin hidden inside.
