This is usually a drum issue or a fuser issue. The cheapest way to troubleshoot this is to try a new toner cart if you see clear evidence of a fault warranting it, but this isn't always the best way; my M401n did something similar with a non-HP toner and it resolved with a new toner, but it was a clear failure of the drum. It turns out both my test toner (a end user refilled abomination I got with my backup M401 I have since thrown out because it was done such that they refilled an 80A without likely dumping the waste toner); see here: Image ghosting - what caused this?
I neglected to update it, but toner fixed it. You want to check for drum defects and evidence of leaks.
Bad toner (came out of my Lexmark color laser, but this defect is universal):
Good toner:
If the issue persists or it's too unclear, do a "halfway test" -- run a test document, and pull the paper before it can fuse. If you do not see the defect, the fuser is pressing it into the page; likewise, if it's there, the fuser is fine and the toner is bad; it could be something like the wiper blade or other rollers like the sponge roller causing the defect to occur. However, it's usually a problem with the toner causing it before due to a minor issue that's not severe enough to put a toner cloud inside. Since this is on the back, handle the page with extra care as the toner has not yet fused to the page. Use as little complexity as possible considering this.

The HP Laserjet 2055d, much like a skilled artist, uses an intricate interplay of components to create its prints. At the heart of this process is the toner cartridge and the transfer belt2. The toner cartridge contains the ink that the printer uses to create images and text, while the transfer belt helps to apply this toner evenly across the page3. If either of these components is damaged or malfunctioning, it can result in unwanted marks appearing on the printouts.
