Abstract
An image forming apparatus includes an image former that forms and fixes an image of the adjustment chart on the sheet, an image reader that reads the adjustment chart formed on the sheet, a front and back adjuster that performs the front and back adjustment on a basis of the adjustment chart that is formed and fixed by the image former and read by the image reader, an image coverage rate calculator that calculates in advance an image coverage rate of the sheet included in one job to be executed by the image former, and a chart coverage rate determiner that determines a coverage rate of the adjustment chart to be formed on a front side of the sheet on a basis of the image coverage rate calculated by the image coverage rate calculator.
Claims12
An image forming apparatus that performs front and back adjustment of images to be formed on both sides of a sheet by using an adjustment chart,
- the image forming apparatus comprising:
- an image former that forms and fixes an image of the adjustment chart on the sheet;
- an image reader that reads the adjustment chart formed on the sheet;
- a front and back adjuster that performs the front and back adjustment on a basis of the adjustment chart that is formed and fixed by the image former and read by the image reader;
- an image coverage rate calculator that calculates in advance an image coverage rate of the sheet included in one job to be executed by the image former;
- and
- a chart coverage rate determiner that determines a coverage rate of the adjustment chart to be formed on a front side of the sheet on a basis of the image coverage rate calculated by the image coverage rate calculator.
The image forming apparatus according to claim wherein
- an image of a sheet is used as the adjustment chart, the sheet having a highest coverage rate among the image coverage rates of the sheets included in the one job, the image coverage rates each being calculated by the image coverage rate calculator.
An image adjustment method for performing front and back adjustment of images to be formed on both sides of a sheet by using an adjustment chart,
- the image adjustment method comprising:
- calculating in advance an image coverage rate of the sheet included in one job to be executed by an image former, by an image coverage rate calculator included in an image forming apparatus;
- determining a coverage rate of the adjustment chart to be formed on a front side of the sheet on a basis of the image coverage rate calculated by the image coverage rate calculator, by a chart coverage rate determiner included in the image forming apparatus;
- forming and fixing an image of the adjustment chart on the sheet, by the image former included in the image forming apparatus;
- reading the adjustment chart formed on the sheet, by an image reader included in the image forming apparatus;
- and
- performing the front and back adjustment on a basis of the adjustment chart that is formed and fixed by the image former and read by the image reader, by a front and back adjuster included in the image forming apparatus.
A non-transitory recording medium storing a computer readable program causing a computer included in an image forming apparatus that performs front and back adjustment of images to be formed on both sides of a sheet by using an adjustment chart to execute:
- calculating in advance an image coverage rate of the sheet included in one job to be executed by an image former, by an image coverage rate calculator included in an image forming apparatus;
- determining a coverage rate of the adjustment chart to be formed on a front side of the sheet on a basis of the image coverage rate calculated by the image coverage rate calculator, by a chart coverage rate determiner included in the image forming apparatus;
- forming and fixing an image of the adjustment chart on the sheet, by the image former included in the image forming apparatus;
- reading the adjustment chart formed on the sheet, by an image reader included in the image forming apparatus;
- and.
- performing the front and back adjustment on a basis of the adjustment chart that is formed and fixed by the image former and read by the image reader, by a front and back adjuster included in the image forming apparatus.
