Another vote for bent inner and outer pulley cages. Rear pulley will not run in plane with the front one.
There also appears to be visible witness marks on the inside of each cage, indicating greater-than-usual chain wear.
You can try to bend it out if you take both cages off, but the accuracy of straightening the outer one will almost certainly affect the inner. The inner is more likely to bend and twist to conform to the much stiffer outer plate.
