Abstract
An image forming apparatus for forming an image on a recording medium by ejecting drops of recording fluid from a recording head includes a waste tank having a space for containing waste fluid, a part for obtaining a correlation value that has a correlation to a deposited state of the waste fluid in the space within the waste tank, and a part for judging whether or not the correlation value exceeds a reference value.
Claims11
An image forming apparatus for forming an image on a recording medium by ejecting drops of recording fluid from a recording head, comprising:
- a waste tank having a space for containing waste fluid;
- obtaining means for obtaining a correlation value that has a correlation to a deposited state of the waste fluid in the space within the waste tank;
- and
- judging means for judging whether or not the correlation value exceeds a reference value,
- wherein the reference value is changed based on a recovery process frequency at which the recovery process is carried out.
