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.
