<p>n electrostatic transfer printing apparatus using a powder developer comprises a transfer printing carrier (107) capable of moving between a photosensitive drum (104) and an object to be printed (112). The transfer printing carrier (107) is provided with a transfer printing surface for attracting toner thereon. When the transfer printing surface faces the photosensitive drum (104), the toner on the photosensitive drum (104) is transfer-printed onto the transfer printing surface. The transfer printing carrier (107) is further provided with a charge loading device (110) thereon, so that when the transfer printing surface is located above the object to be printed (112), the charge loading device (110) applies a voltage which has the same charge polarity as that of the toner to the back of the transfer printing surface. By means of coordination between the transfer printing carrier (107) and the charge loading device (110), the transfer printing apparatus can achieve the transfer of the toner between the transfer printing carrier (107) and the object to be printed (112) and can print on objects of a certain thickness or of irregular shape.</p> |
