Decoloring apparatus

A decoloring apparatus, comprising:

• a decoloring assembly configured to heat an image receiving medium on which an image is formed by a decolorable color material at a predetermined set temperature;
• a driver configured to drive the decoloring assembly at a predetermined conveyance speed;
• a storage configured to store:
• first setting information, being setting information when there is no next job, in which a set temperature of the decoloring assembly for each of plural coverage rates of the image receiving medium and a conveyance speed of the driver are associated with each other, and
• second setting information, being setting information when there is a next job, in which a set temperature of the decoloring assembly for each of plural coverage rates of the image receiving medium and a conveyance speed of the driver are associated with each other;
• a controller configured to:
• perform control to drive the decoloring assembly based on the conveyance speed and the set temperature corresponding to a predetermined coverage rate of the image receiving medium in the first setting information stored in the storage when there is no next job, or
• perform control to drive the decoloring assembly based on the conveyance speed and the set temperature corresponding to a predetermined coverage rate of the image receiving medium in the second setting information stored in the storage when there is a next job;
• and
• a plurality of cassettes,
• wherein the controller is configured to set a coverage rate of the image receiving medium stored in the cassette for each cassette and to perform control to decolor an image receiving medium from a cassette set for housing an image receiving medium with a low coverage rate,
• wherein each of the plurality of cassettes has a remaining amount detection sensor configured to detect a remaining amount of the image receiving medium, and
• when the remaining amount detection sensor detects that the remaining amount of an image receiving medium with predetermined coverage rate in a cassette accommodating the image receiving medium is equal to or less than a predetermined amount, the controller is configured to perform control to drive the decoloring assembly based on a set temperature and a conveyance speed when the coverage rate is higher than the predetermined coverage rate from the first setting information stored in the storage.
