While browsing a website about Disney comics, I stumbled upon a index for Roger Rabbit comics which seems to be pretty extensive. Here is a listing for every story and issue featuring the character(The movie adaptation, Resurrection of Doom, RR, Toontown etc)
Index that only lists the Roger Rabbit issues.
And one for Roger Rabbit's Toontown.
To see more details or pictures from each story, click on "story code". The scans are very small, but the links are worth checking out if you like me, are a huge Roger Rabbit enthusiast.
