Abstract
A pressure lever includes an oscillating edge that is capable of contacting a supporting shaft of a pressure roller. An oscillating lever includes a plurality of oscillating edges around a fixed edge. An elastic unit is latched between the fixed edge of the oscillating lever and an immovable portion, and biases the oscillating lever towards one of the rollers. A position of the fixed edge of the oscillating lever is capable of being changed in a state of being deviated from a position before oscillating based on an oscillating position of the oscillating lever separately from an oscillation of the fixed edge.
