Abstract
The present invention provides an apparatus wherein image fixing means is controlled for different fixing conditions under which a toner image is fixed on a recording material to adapt it to a synthetic resin sheet as the recording material or to a color image to be fixed, including at least one of fixing temperature, fixing speed and actuation of cleaning means. The present invention is particularly effective in use for a recording system in which the fixing temperature and speed are decreased and the cleaning means is actuated when a color image is to be formed on a transparent or resin sheet. The present invention is most useful for a color image recording system.
Claims24
A recording apparatus comprising:
- means for forming a toner image;
- a pair of rotatable members for gripping and conveying a recording material to heat and fix said toner image on said recording material;
- means for heating at least one of said rotatable members;
- means for rotating said rotatable members;
- means for setting a first fixing condition capable of fixing said toner image onto a said recording material which is a synthetic resin film;
- means for setting a second fixing condition capable of fixing said toner image onto a said recording material when it is a sheet of paper, the first fixing condition providing a rotational speed of said rotatable members lower than that of the rotatable members under the second fixing condition;
- means for generating a signal indicative of the recording material being the synthetic resin film;
- and
- means for selecting the first fixing condition in response to said signal.
A recording apparatus comprising:
- means for forming a toner image;
- fixing means including a rotatable fixing member for heating and fixing said toner image onto a recording material;
- means for heating said rotatable fixing member;
- means for controlling surface temperature of said rotatable fixing member;
- means for controlling peripheral speed of said rotatable fixing member;
- and
- selector means for setting the surface temperature and peripheral speed of said rotatable fixing member in accordance with the sort of said recording material, the set temperature and speed being together increased or decreased.
A recording apparatus comprising:
- means for selectively forming a monochromatic or multi-color toner image;
- fixing means including a rotatable fixing member for fixing the toner image formed by said toner image forming means onto a recording material;
- means for controlling the peripheral speed of said rotatable fixing member;
- means for cleaning the surface of said rotatable fixing member;
- and
- selector means for separating said cleaning means from said rotatable fixing member upon the monochromatic toner image fixing and for engaging said cleaning means with said rotatable fixing member upon multi-color toner image fixing.
A recording apparatus comprising:
- means for forming a toner image;
- fixing means including a rotatable fixing member for fixing said toner image onto a recording material and means for cleaning said rotatable fixing member;
- means for generating a signal representing that said toner image is to be fixed to the recording material which is in the form of a synthetic resin material;
- means for setting a first cleaning mode in which said cleaning means acts on said rotatable fixing member when said toner image is to be fixed to the synthetic resin film and a second cleaning mode in which said cleaning means is separated from said rotatable fixing member to its inoperative position when said toner image is to be fixed to a sheet of paper as a recording material;
- and
- means for changing said setting means into the first cleaning mode in accordance with said signal.
