ABSTRACT:
A fixing-roller pressing mechanism for a copying machine containing the following: upper and lower fixing rollers; a lower frame flexibly held by the lower half of the copying machine, which is split into upper and lower halves, so that the lower frame can move vertically and pivotally hold the lower roller; an upper frame pivotally held by the lower half so that it can rotate and pivotally hold the upper roller; a member installed in the upper half, which causes the upper roller to press against the lower roller via the upper frame when the upper half is closed; and retention system installed between the lower and upper halves, which causes the upper roller to remain in the half-pressed state against the lower roller when the upper half is open.
