  • Patent number: 8159689
    Abstract: An image forming apparatus that can reduce a difference in fog or image density between two facing pages of a booklet formed after duplex printing is provided. A CCD line sensor inputs a series of pieces of image data whose order of printing has been determined in advance. The CCD line sensor, a first storage section, a second storage section, and a calculation section determine a difference in printing density between the first face and the second face of the printing medium after duplex printing. A judgment section judges whether or not to change the order of printing based on the difference in printing density. A control unit controls the order of printing of the image data based on the judgment. An image forming section, a paper supply section, an image reading section, and an operation section print the image data on the printing medium.

  • Patent number: 7646997
    Abstract: A toner replenishing device of a toner consumption calculating portion calculates a toner consumption using a gray scale value of each pixel in a multiple-value image inputted from an image data input portion. The calculated toner consumption is corrected by a corrected consumption calculating portion, and is then accumulated by a cumulative consumption calculating portion, and thereby a cumulative toner consumption is calculated. A main replenishing amount control portion controls a replenishing roller driving motor so as to replenish a predetermined first replenishing amount of a toner to a developing tank when the cumulative toner consumption reaches a reference consumption or more. Further, an auxiliary replenishing amount control portion controls the replenishing roller driving motor so as to start to replenish a predetermined second replenishing amount of a toner to the developing tank when a toner concentration obtained by a toner concentration obtaining portion reaches less than a start concentration.

  • Patent number: 7536138
    Abstract: In the development apparatus and the image forming apparatus of the present invention, a first regulation member for regulating an upper surface of developer is provided on an adjacent and downstream portion with respect to a developer outlet in terms of travel direction of developer. The amount of developer passing below the first regulation member is thus adjusted. On this account, the present invention provides a development apparatus and an image forming apparatus capable of maintaining appropriate amount of developer in the developer container by reducing influence of developer fluidity or the like. With stable stirring performance and development performance, the development apparatus and the image forming apparatus of the present invention perform secure development, including the time period until the extra developer overflows and is discharged.
