Abstract: An information processing apparatus for communicating to and from a database having stored therein information on errors which have occurred in an image forming apparatus, the information processing apparatus includes at least one processor configured to acquire, from the database, information on a certain error and information on a related error which has occurred in past before the certain error, acquire first information related to a cumulative number of printed sheets of the image forming apparatus at a time of occurrence of the certain error, and second information related to a cumulative number of printed sheets of the image forming apparatus at a time of occurrence of the related error, and determine a causal part of a cause of the certain error based on the first information and the second information, and an output unit configured to output the causal part of the cause of the certain error.

Abstract: Provided is an image forming apparatus, which is configured to form measurement images for detecting color misregistration exhibited in a main scanning direction on an intermediate transfer belt in the order of: a measurement image of a reference color, a measurement image of a second color, a measurement image of the reference color, a measurement image of a third color, a measurement image of the reference color, a measurement image of a fourth color, and a measurement image of the reference color in a sub-scanning direction. The image forming apparatus is also configured to detect the measurement images for detecting color misregistration over an entire area of the intermediate transfer belt in the main scanning direction by a line sensor unit, and to correct color misregistration exhibited in the main scanning direction based on detection results.

Abstract: A low density area is caused at a trailing edge of an image formed on a photosensitive drum. This low density area is less likely to be caused when the density of the image is higher and the humidity is lower. To prevent generation of such low density area, if a color misregistration detection toner pattern having a high density is formed, in a low humidity environment, an excessively large amount of toner is consumed unnecessarily. In response, the density of the color misregistration detection toner pattern is adjusted based on the humidity.
