An image forming apparatus includes a correction unit configure to correct image data based on a correction condition; an image bearing member; an image forming unit configured to form an image on the image bearing member, based on the corrected image data; a transfer unit configured to transfer the image onto a recording material; a measurement unit configured to measure a measurement image formed on the image bearing member; and a converting unit configured to convert, based on a conversion condition, a measurement result of the measurement image measured by the measurement unit.

A printer controller controls the image forming unit to form the measurement image, control the measurement unit to measure the measurement image, control the converting unit to convert the measurement result of the measurement image, and generate the correction condition based on the measurement result converted by the converting unit.

An accommodating container includes a flexible pouch including a bottom portion and a side portion extending from the bottom portion so as to form an opening and a communicating member disposed inside the side portion on a side of the opening and provided with a communicating portion communicating between inside and outside of the pouch. The communicating member includes an opposite surface opposing the bottom portion, and the side portion includes a fold forming portion forming a folding shape along an edge portion of the opposite surface of the communicating member.

In an example of a method for reducing contamination, a purified imaging oil is formed by filtering an imaging oil through an imaging oil filter, and then filtering the imaging oil through a polar absorbent filter. A surface of an amorphous silicon photoconductor of a liquid electrophotographic printing apparatus is maintained by periodically applying the purified imaging oil to the amorphous silicon photoconductor.

In an example, a print agent application assembly includes a print agent transfer roller to receive print agent and transfer a portion of the print agent to a photoconductive surface and a print agent regulator roller to regulate a film thickness of print agent on the print agent transfer roller. The print agent regulator roller may include a nip forming region and a first mounting region. The print agent application assembly may further include a first resilient component which spans a diametrical width of the print agent regulator roller and acts on the print agent regulator roller outside the nip forming region to impart a lateral force to the first mounting region, the lateral force urging the print agent regulator roller towards the print agent transfer roller.

A method, a system and a recording medium for rendering a macro gloss effect using a digital front end processor and a color printer having color marking materials involve defining a vector pattern cell, and creating a pattern ink based on the vector pattern cell. The pattern ink can be constrained to write at or near an ink limit at small sizes varying from a high toner pile to a lower toner pile within a pattern ink cell based on the vector pattern cell. One or more objects and a background can be then painted with the pattern ink to create a macro gloss effect image based on the pattern ink.
