An image drum presses and transfers an ink image formed on the surface thereof onto an image receiving medium, and an image system having the same of a solid inkjet image forming apparatus. The image drum includes a first cylindrical body which forms an image on the surface thereof and transfers the image onto an image receiving medium by pressure; a heat generator formed in the first cylindrical body which heats the first cylindrical body; a space part formed between the first cylindrical body and the heat generator; and including a certain amount of operational fluid transferring heat between the first cylindrical body and the heat generator. The operational fluid is contained between the first cylindrical body and the heat generator. Accordingly, when the image drum is heated, the surface temperature of the image drum can be precisely and uniformly controlled, power consumption decreases, and heat is efficiently transmitted.

A safety knob is installed at a switch knob for sliding along the surface of the switch knob. A safety lock bar integrally formed at the safety knob for sliding with the safety knob, a plate spring restoring the safety lock bar to the original disposition, and a locking rod locking the safety lock bar for preventing the switch knob from being pressed unless the safety knob is manipulated is disclosed. The structure provides a facilitation of the manipulation during an emergency situation by either locking or unlocking the safety system via a driver's manual operation and/or prevention of a manipulation error of the instrument switch by operating the safety lock function in both an activated/deactivated state of the instrument switch.

Disclosed are a bookbinding unit and an image forming apparatus having the same. The bookbinding unit includes a bookbinding unit main body, a pair of stack trays disposed in the bookbinding unit main body so as to support print media on the upper surfaces of the stack trays and a folding knife movable in the space between the pair of the stack trays to fold the print media on the stack trays and to move the folded print media into the space between the pair of the stack trays. The pair of the stack trays is rotatable in conformity with the movement of the print media into the space between the stack trays to provide a surface contact guiding of the folded print media.
