  • Patent number: 9332153
    Abstract: In an image reading device, a reading control portion reads image data for one line in a main scanning direction from a first reference member having a reference color. A storage portion stores initial reference data for one line generated based on image data for a plurality of lines read from a second reference member by using an image reading portion while a surface of the second reference member having the reference color is moving in a sub scanning direction perpendicular to the main scanning direction. A reference data generation portion generates reference data based on the image data read by the reading control portion and a high-frequency component of the initial reference data stored in the storage portion. A shading correction portion performs shading correction for image data read from a document by the image reading portion, based on the reference data generated by the reference data generation portion.

  • Patent number: 9304470
    Abstract: An image forming apparatus is provided which shortens the time for image formation, thereby improving the convenience. To achieve this, the control part of the image forming apparatus has a job data acquisition part and a conveyance speed control part. The job data acquisition part acquires job data from an operation panel part, a document reading part, an external terminal, or the like. The conveyance speed control part measures the temperature of a temperature sensor at the time of initial start-up operation of conveying a recording sheet, and at the time when the recording sheet has reached a registration roller pair, respectively. Further, the conveyance speed control part selects whether or not to wait for a prescribed waiting time and whether or not to reduce the fixing speed below a normal speed, according to a condition corresponding to the respective measured temperatures.
