A method for training an image generation model, an image generation method, device and apparatus, and a storage medium. The method for training an image generation model comprises: acquiring a first image set and a second image set, the first image set comprising multiple captured images, and the second image set comprising multiple cartoon images; performing pre-processing of the captured images according to a preset cartoon generation algorithm to obtain corresponding target cartoon images; and iteratively training a generative network and a discriminative network in an alternating manner to obtain an image generation model.
