Image forming apparatus, image forming method, and computer-readable medium

An image forming method executed by an image forming apparatus having a tank configured to hold liquid, one or more channel pipelines communicating with the tank, and at least one liquid discharge head connected to the one or more channel pipelines and configured to discharge the liquid held in the tank, the image forming method comprising:

• detecting a discharge amount of liquid discharged per predetermined time period from the at least one liquid discharge head;
• adjusting the discharge amount;
• and
• in a case where a total amount of liquid discharged from all of the at least one liquid discharge head connected to the one or more channel pipelines until a predetermined first time period elapses from a first time is a first discharge amount and a total amount of liquid discharged from all of the at least one liquid discharge head connected to the one or more channel pipelines until the first time period elapses from a second time later than the first time by the first time period is a second discharge amount, adjusting the discharge amount from a time later than the second time by the first time period, based on a value obtained by subtracting the second discharge amount from the first discharge amount.

A non-transitory computer-readable medium including programmed instructions that cause a computer configured to control an image forming apparatus including a tank configured to hold liquid, one or more channel pipelines communicating with the tank, and at least one liquid discharge head connected to the one or more channel pipelines and configured to discharge the liquid held in the tank, to function as:

• a detection unit configured to detect a discharge amount of liquid discharged per predetermined time period from the at least one liquid discharge head;
• and
• a control unit configured to adjust the discharge amount, wherein
• in a case where a total amount of liquid discharged from all of the at least one liquid discharge head connected to the one or more channel pipelines until a predetermined first time period elapses from a first time is a first discharge amount and a total amount of liquid discharged from all of the at least one liquid discharge head connected to the one or more channel pipelines until the first time period elapses from a second time later than the first time by the first time period is a second discharge amount, the control unit is configured to adjust the discharge amount from a time later than the second time by the first time period, based on a value obtained by subtracting the second discharge amount from the first discharge amount.
