Abstract
An electrostatographic printing apparatus comprises a charge receptor, and a transfer station for transferring a toner image from the charge receptor to a sheet. The sheet passes through a nip formed between the charge receptor and a moving transfer belt. Upstream of the nip, the belt forms a shallow angle relative to the charge receptor; downstream of the nip, the belt forms a steep angle relative to the charge receptor. This configuration enables self-stripping of the sheet from the transfer belt at the exit of the nip.
