Abstract
An image forming apparatus includes: an image carrier; a lubricant applicator that applies a lubricant to the image carrier; a hardware processor; and a density unevenness measurer that is provided in the image forming apparatus or outside the image forming apparatus, and measures a first density unevenness for at least one of the density unevenness measurement image formed by the image former in the application unevenness detection mode or a density unevenness measurement image obtained by primary or subsequent transfer of the density unevenness measurement image, wherein the hardware processor detects the application unevenness of the lubricant applied by the lubricant applicator based on the first density unevenness measured by the density unevenness measurer.
Claims28
An image forming apparatus having an application unevenness detection mode, the image forming apparatus comprising:
- an image carrier;
- a lubricant applicator that applies a lubricant to the image carrier;
- a hardware processor that is capable of changing an application amount of the lubricant applied to the image carrier by the lubricant applicator, and detects an application unevenness of the lubricant applied by the lubricant applicator;
- an image former that forms an image on the image carrier to which the lubricant has been applied by the lubricant applicator, and forms, in the application unevenness detection mode, a density unevenness measurement image on the image carrier in a state where the application amount of the lubricant applied to the image carrier is changed by the hardware processor in association with a temporal change in the application amount;
- and
- a density unevenness measurer that is provided in the image forming apparatus or outside the image forming apparatus, and measures a first density unevenness for at least one of the density unevenness measurement image formed by the image former in the application unevenness detection mode or a density unevenness measurement image obtained by primary or subsequent transfer of the density unevenness measurement image, wherein
- the hardware processor detects the application unevenness of the lubricant applied by the lubricant applicator based on the first density unevenness measured by the density unevenness measurer.
A non-transitory recording medium storing a computer readable program for causing a computer of an image forming apparatus having an application unevenness detection mode and including an image carrier and a lubricant applicator that applies a lubricant to the image carrier to execute:
- changing, in the application unevenness detection mode, an application amount of the lubricant applied to the image carrier by the lubricant applicator in association with a temporal change in the application amount;
- forming an image on the image carrier to which the lubricant has been applied by the lubricant applicator, and forming, in the application unevenness detection mode, a density unevenness measurement image on the image carrier in a state where the application amount of the lubricant applied to the image carrier is changed;
- and
- detecting an application unevenness of the lubricant applied by the lubricant applicator based on a first density unevenness measured for at least one of the density unevenness measurement image formed on the image carrier in the forming the density unevenness measurement image, or a density unevenness measurement image obtained by primary or subsequent transfer of the density unevenness measurement image.
