ABSTRACT:
An image forming apparatus includes a movable image carrying member, a latent imager for forming a latent image on the image carrying member, a developer for developing the latent image by a toner, a transferrer for transferring a toner image on the image carrying member formed by the developer to an image supporting member at a transfer position, a carrier for carrying the image supporting member and for conveying the image supporting member to the transfer position in order to perform the transfer, and an adsorption device for causing the image supporting member to be electrostatically adsorbed onto the carrier by supplying the image supporting member with electric charges, a detector for detecting a kind of an image supporting member to be adsorbed, and a controller for controlling an electric-charge supply amount by the adsorption device according to the kind of image supporting member detected by the detector.
