Abstract
An image forming apparatus according to an embodiment includes a fixing section that fixes a toner image formed on a sheet. A controller controls a preliminary rotation of the fixing section after execution of a first image forming job and before execution of a second image forming job. Conditions for the preliminary rotation include types of sheets used in the first image forming job and the second image forming job, respectively, and a number of sheets used in executing the first image forming job.
Claims8
An image forming apparatus, comprising:
- a fixing section configured to fix a toner image formed on a sheet;
- and
- a processor programmed to determine an execution time of a preliminary rotation of the fixing section and control the preliminary rotation of the fixing section for the determined execution time after execution of a first image forming job for performing image formation on a first sheet type having a first sheet width and before execution of a second image forming job for performing image formation on a second sheet type having a second sheet width longer than the first sheet width, the execution time being determined based on conditions including:
- a thickness of the first sheet type used in the first image forming job and a thickness of the second sheet type used in the second image forming job, and
- a number of sheets of the first sheet type used in execution of the first image forming job.
A method of controlling a fixing section for fixing a toner image on a sheet, the method comprising:
- executing a first image forming job for performing image formation on a first sheet type having a first sheet width;
- determining a thickness of the first sheet type used in the first image forming job and a thickness of a second sheet type to be used in a second image forming job, the second sheet type having a second sheet width longer than the first sheet width;
- determining a number of sheets of the first sheet type used in executing the first image forming job;
- and
- controlling an execution time of a preliminary rotation of the fixing section after execution of the first image forming job and before execution of the second image forming job that performs image formation on a second sheet type having a second sheet width longer than the first sheet width, the execution time being determined based on the based on conditions including:
- a thickness of the first sheet type used in the first image forming job and a thickness of the second sheet type used in the second image forming job, and
- a number of sheets of the first sheet type used in execution of the first image forming job.
