Abstract
An image forming apparatus includes at least a first image-forming unit provided with a first latent image-holding member, a first latent image-forming device, a first developing device for developing a first latent image with a first toner to form a first toner image, and a first image-transfer device for transferring the first toner image to an image-receiving member, and a second image-forming unit provided with a second latent image-holding member, a second latent image-forming device, a second developing device for developing a second latent image with a second toner to form a second toner image, and a second image-transfer device for transferring the second toner image to the image-receiving member holding the first toner image. The second developing device also serves as a cleaning device for recovering the toner remaining on the second latent image-holding member after the transfer to perform cleaning. The second latent image-holding member has a surface having a contact angle for water of not less than 85.degree..
