A transfer mechanism includes: a transfer unit having a transfer belt; and
a belt contact and separation assembly for bringing the transfer belt
into, and separating it away from, an electrostatic latent image support
by shifting the position of the transfer unit. The belt contact and
separation assembly includes: a multiple number of transfer unit shifters
that abut the transfer unit and shift the position of the transfer unit;
a multiple number of linkage members that link with the plural transfer
unit shifters, correspondingly; an elastic member for coupling the plural
linkage members; and a driver for actuating the transfer unit shifters
through the linkage members.
