Dennis O'Neil, who wrote the first issue of the series, recounted that "I stopped by Julie [Schwartz, Batman editor]’s office, and he said, ‘We’re going to do a Joker book.’ I know that alarms went off, I could sense the problems that such a thing would entail … but it was a job.” The series was launched in May 1975 by O'Neil and artist Irv Novick. In order to have him work as a protagonist, writers on the series toned down the Joker's insanity and to adhere to the Comics Code Authority, each issue would end with the Joker being apprehended, only to escape at the beginning of the next issue. Batman did not appear in the series, and the Joker was forbidden to murder anyone in the pages of his own magazine.

The letters page of The Joker #9 (Sept.–Oct. 1976) mentions that Martin Pasko was writing a Joker vs. the Justice League of America story titled "99 and 99/100 Percent Dead!" to appear in The Joker #10, which was never published. In the end notes of The Greatest Joker Stories Ever Told (1989) it is noted that The Joker editor Julius Schwartz had no recollection of this story ever being completed. However, Pasko found xeroxed pages of the story which he sold on eBay in 2011. A cover for issue #10 was drawn by Ernie Chan, but it was never finished.  The Joker #10 story is slated to be published for the first time in DC's The Joker: Bronze Age Omnibus, which also contains The Joker #1 through #9 as well as other published Joker stories from the 1970s.

It may have been an unusual idea at the time, but writer Denny'Oneil and artist Irv Novick decided to feature a villain in his own comic book. The Joker only lasted nine issues.CS1 maint: Extra text: authors list (link)
