摘要： An image forming apparatus includes a sensor that acquires first and second data groups of paper characteristics by measuring a recording medium; a processor that determines a parameter for controlling at least one of image formation and conveyance of a recording medium on a conveyance path based on the first and second data groups acquired by the sensor; an image former that forms an image on a recording medium conveyed on the conveyance path based on the parameter. The processor compares the first and second paper characteristic data groups, the first paper characteristic data group has been measured at a first time period and the second paper characteristic data group has been measured at a second time period nearer to a present time than the first time period, and the processor controls the image formation based on a the comparison result.

摘要： Provided is a recording medium detection device which prevents a recording medium from jamming. The device comprises: a first roller and a second roller which nip and transport a recording medium; a roller shaft which rotatably supports the second roller; a shaft support; and a displacement detector. The shaft support supports the roller shaft movably in the thickness direction of the recording medium. The displacement detector detects displacement of the second roller in the thickness direction. The shaft support further supports the second roller movably in the transportation direction of the recording medium through the roller shaft.

摘要： Provided is a recording medium detection device which prevents the decline in productivity. The recording medium detection device comprises a first detecting section and a second detecting section. The first detecting section performs a first adjustment process and makes a detection of a recording medium being transported. The second detecting section is located more downstream than the first detecting section in the transportation direction of the recording medium, performs a second adjustment process which takes a longer time than the first adjustment process, and makes a detection of the recording medium being transported.

摘要： An image reading apparatus 300 comprises: the scanner device SD which reads information about a sheet P conveyed on a paper conveying route PP and information about a position, a form and a color of an image formed on the sheet P; a spectrophotometer CI which reads information about a color of an image formed on a sheet P conveyed on the paper conveying route PP; and a support base TR which incorporates the paper conveying route and a motor for conveying a sheet and can be pulled out from a main body together with the paper conveying route and the motor. The scanner device SD is not mounted on the support base TR but fixed to the main body of the image reading apparatus. The spectrophotometer CI is mounted on and fixed to the support base TR, and spaced from the paper transfer route PP by a predetermined distance.
