Abstract: An information processing apparatus includes the following elements. A selector selects, as a first item, an item disposed within a QFD chart. A first calculator calculates a correlation score between the first item and an item associated with an adjacent axis. A first extracting unit compares the correlation score with a predetermined value and extracts a second item related to the first item. A second calculator calculates a correlation score between the second item and an item associated with an adjacent axis and determines the calculated correlation score between the item associated with the adjacent axis and the first item. A second extracting unit compares the correlation score with a predetermined value and extracts a third item related to the first item. A display unit displays the first item, the second item, and the third item in a mode different from a mode of the other items.

Abstract: A process for producing an electrophotographic photoreceptor including a step of coating a light-sensitive layer on an electroconductive base, a step of removing part or all of oxidants present from an air atmosphere by an oxidants removing unit, a step of dealing with a coating solution for forming the light-sensitive layer in the air atmosphere from which concentration of oxidants is suppressed by the step of removing part or all of oxidants present, and a step of suppressing variation in the concentration of oxidants in the air atmosphere, wherein the step of dealing with the coating solution for the light-sensitive layer includes at least one of the steps of preparing the coating solution for forming the light-sensitive layer, applying the light-sensitive layer and drying an applied coating.
