ABSTRACT:
An image forming device includes a process unit having a photoconductive drum that is inserted and removed with respect to a device main body from a front side thereof in an axial direction of the photoconductive drum. The device main body includes a transfer roller that nips printing paper with the photoconductive drum and transfers a toner image on a surface of the photoconductive drum onto the printing paper. A transfer guide supports the transfer roller and is capable of being slanted in a direction in which the transfer roller and the photoconductive drum make contact with one another and separate from one another. An elastic member urges the transfer roller in a direction to make contact with the photoconductive drum. An operation member slants the transfer guide against an urging force of the elastic member by an operation from the front side of the device main body.
