Abstract:
1. A complex image forming apparatus comprising: a supplying unit supplying a printing medium; a transfer path via which the printing medium supplied by the supplying unit is transferred; a thermal printing engine disposed on the transfer path for performing color printing by heating a thermal imaging printing medium having one or more image forming layers; a laser printing engine disposed on the transfer path on which the thermal printing engine is installed for performing printing on the supplied printing medium by electrophotolithography; and an exiting unit for receiving the printing medium exited via the transfer path; wherein the complex image forming apparatus performs multi-color printing on the thermal imaging printing medium using the thermal printing engine and single color printing on different printing media using the laser printing engine; the laser printing engine comprises: a developing unit comprising a toner container in which toner of a predetermined color is stored and an image forming portion to which the toner is supplied from the toner container and which contributes to image formation; a light scanning unit for forming an electrostatic latent image by scanning light on the image forming portion; a transfer unit disposed to face the image forming portion for transferring the image formed by the image forming portion onto a printing medium; a fusing unit having a fusing roller and a pressing roller for fusing the image transferred onto the printing medium; and first and second contact-adjusting units respectively adjusting contact between the fusing roller and the pressing roller and contact between the transfer unit and the photosensitive medium.
