摘要： An image forming apparatus having a developing device of the type using a two-component type developer and developing an electrostatic latent image by a bias electric field having an alternating electric field. A predetermined reference latent image is electrostatically formed on an image carrier by a reference latent image forming device and then developed by the developing device to become a reference toner image. An irregularity detecting circuit determines the degree of difference between the density of the edge and the density of the central portion of the reference toner image. A bias electric field control circuit controls the bias electric field in matching relation to the output of the irregularity detecting circuit, thereby preventing the image quality from being degraded by a change in the resistance of the carrier.

摘要： An image reading device capable of preventing, by increasing the quantity of light at the center or bound portion of a spread book document, the quantity of light from becoming short and preventing density from becoming irregular due to the deviation of a focus. At and around the center of a spread book document where the document is bound, the quantity of light for illumination or the amplification gain of image data read from the document is increased. A plurality of fluorescent lamps illuminate the surface of the document at the upstream side and downstream side with respect to an intended scanning direction. When the edge of the document is to be detected, only one of the lamps is turned on to enhance the stripe pattern representative of the stepped edge portion of the document.

摘要： In a book document reading device having a page turning capability, a turn belt has a flat portion at the underside thereof and is supported by a turn roller. The turn roller selectively moves the turn belt to a first position where the flat portion of the belt electrostatically attracts the uppermost leaf of a book document, which is spread on a table, in contact with the leaf, or to a second position where the belt is spaced apart from the book document while carrying the uppermost page therewith. When the turn belt is moved from the first position to the second position, a scanning unit is caused to stop moving. This allows the leaf of the document to surely adhere to the turn belt.
