Abstract: Focus adjustment of an optical writing unit is performed based on an image of a test pattern formed on a paper sheet. The pattern includes bars of density levels associated with adjustment quantity information indicating numerical values corresponding to the numbers of rotation of adjustment motors and adjustment screws. The density levels decrease as the amount of displacement of the unit with respect to a photosensitive drum increases. A focus adjustment device accepts an input of the numerical values indicated beside the unprinted bars of the lowest density levels and causes the motors to turn by the numbers of rotation indicated by the input numerical values to move the unit to the position of correct focus. It is possible to perform focus adjustment of the unit with ease and high accuracy regardless of whether the unit is for forming binary or multi-valued images.

Abstract: An object of the invention is to reproduce a faithful image irrespective of thermal expansion of a light-scanning unit and to reproduce a faithful image without enhancing the strength of the light-scanning unit excessively. A pair of supporting portions of a light-scanning unit, each having a flat face, are supported in linear contact with a right column-shaped supporting member provided with the apparatus body. The light-scanning unit is provided on the supporting member near to a starting position where writing image data on a photosensitive body with a scanning line is started in a main scanning direction so as not to be mutually displaced relative to the supporting member. Thereby, the light-scanning unit is allowed to extend in the longitudinal direction of the supporting member due to thermal expansion of the light-scanning unit. Also, an elongated supporting member made of stainless steel penetrates a base body of a light-scanning unit made of synthetic resin which scans in scanning line of laser light on the photosensitive body to exposure, to support the light-scanning unit. The center of gravity of the light-scanning unit is positioned near to the supporting member and vertically below the supporting member, to make the moment acting on the light-scanning unit small and hold the light-scanning unit in a stable state. The supporting member suppresses deformation of the base body due to thermal expansion.

Abstract: A registration pattern data generating portion is configured of a pattern set data generator for rough order error estimation and a pattern set data generator for fine order error estimation. When an error is estimated, a pattern set for rough order error estimation is checked first so as to roughly determine the size of the error and then another pattern set for fine order error estimation is checked so as to finely determine the size of the error. Thus, checking the two types of pattern sets makes it possible to exactly recognize the error in rough and fine units, providing fast and exact error determination.

Abstract: An image forming apparatus includes a counting section, a storage section, a control section, and a driving member control section. The counting section counts the number of recording media subjected to successive printing. The storage section stores the number counted by the counting section. The control section performs a control process including: setting a power saving mode by selecting a printing speed of the fixing section which is lower than a preset normal speed used in the normal mode while selecting a preset fixing temperature of the fixing section which is lower than a preset normal temperature used in the normal mode when the normal mode is alive while a frequency of successive printing on not more than three recording media is a predetermined percentage or more. The driving member control section switches a current printing speed of the fixing section to a printing speed selected by the control section.
