Jimi joined the ITV soap in December 2013, but his character Kal will bid farewell to the Weatherfield cobbles in a dramatic storyline later this year.
We're told gym owner Kal will be at the centre of a "huge secret plot twist" which will have a huge impact on his family and girlfriend Leanne.
Jimi said: "When I was told about this storyline I felt it was a brilliant way to say goodbye to Kal and I am really looking forward to filming my departure scenes.
"I have had a fantastic 18 months on Coronation Street but I never saw myself staying around forever, my life is in London and I enjoy playing a variety of roles."
Jimi, who is married to Strictly Come Dancing star Flavia Cacace, continued: "I want to thank Stuart and the team for giving me the opportunity to be part of such a fantastic show. This is the longest I have ever been in one job and I have enjoyed it immensely."
Producer Stuart Blackburn said: "Kal's departure will be a big part of the fantastic spring and summer of drama on Coronation Street. We discussed the plot idea with Jimi and we all feel it is a great storyline which will have huge ramifications for the Nazirs and Leanne going forward.
"Jimi is a talented actor and an asset to the show and we will be sorry to see him go, but this is a fantastic exit storyline there are still many twists and turns for the character in the coming months."
Taking to Twitter after making his announcement, Jimi said: "It's been a great ride but time to say F'arewell Kal', some great stuff coming up stay tuned!"
