Abstract: An image forming apparatus includes a developing member, a developer supply unit, a pulsating pump, and a correction unit. The developing member is to be supplied with a liquid developer from a supply member and is configured to develop an electrostatic latent image formed on an image carrier. The developer supply unit forms a closed space together with the supply member. The closed space stores the liquid developer. The pulsating pump is configured to feed the liquid developer to the closed space at a predetermined reference flow rate. The correction unit is configured to make a correction to achieve increase or decrease with respect to the reference flow rate according to presence or absence of image information used for forming the electrostatic latent image, in units of a predetermined processing length in a process direction intersecting a development width on the image carrier.

Abstract: A specification part of an information processing device specifies, by using image data for a correction chart defining a plurality of patch regions having different color values, a target characteristic indicating a relation between the color value and a first colorimetric value of a first patch image as a laminated image of a special color image and a colored image that correspond to each of the patch regions formed by the device through the 2-path printing. A generation part of the device generates a correction table for correcting the color value so that a measured characteristic comes close to the target characteristic, the measured characteristic indicating a relation between the color value and a second colorimetric value of a second patch image as the laminated image corresponding to each of the patch regions formed by the device through the 1-path printing using the image data for a correction chart.

Abstract: A video count value is acquired per unit area predetermined in a direction in which a recording medium is conveyed, based on recording target image data. When an image has been formed on an area of the recording medium from which the video count value has been acquired, control is performed by using the acquired video count value so that a developing unit is replenished with an amount of toner corresponding to the video count value acquired from the area.

Abstract: An image forming system includes a light emitting device, a controller, an image forming device, an acquiring device, a calculator, and a storage device. The controller corrects an amount of light, which is outputted from the light emitting device, based on a first correction value stored in the storage device. The image forming device forms a test image with the amount of light corrected based on the first correction value. The acquiring device acquires density information indicating a characteristic of density of the test image. The calculator calculates a second correction value based on the density information and calculates a third correction value based on the first correction value and the second correction value. The controller corrects the amount of light based on the third correction value. The image forming device forms a target image with the amount of light corrected based on the third correction value.
