Abstract
An image forming apparatus includes an image bearer to bear a visible image, a transfer device to transfer the visible image from the image bearer onto a recording medium, a separator to separate the recording medium from the image bearer, a separation bias application device to apply a separation bias to the separator; and a controller to control the separation bias. When the recording medium fed in the image forming apparatus is either a black sheet or a metallic sheet, the controller sets the separation bias smaller than a predetermined separation bias value for a reference sheet type other than the black sheet and the metallic sheet.
Claims9
An image forming apparatus comprising
- an image bearer to bear a visible image;
- a transfer device to transfer the visible image from the image bearer onto a recording medium;
- a separator to separate the recording medium from the image bearer;
- a separation bias application device to apply a separation bias to the separator;
- and
- a controller to control the separation bias,
- wherein, when either a black sheet or a metallic sheet is fed as the recording medium in the image forming apparatus, the controller sets the separation bias smaller than a predetermined separation bias value for a reference sheet type other than the black sheet and the metallic sheet.
A method of separating a recording medium from an image bearer in an image forming apparatus, the method comprising:
- applying a separation bias to the recording medium;
- recognizing a sheet type of the recording medium;
- and
- reducing the separation bias from a predetermined separation bias value for a reference sheet type other than a black sheet and a metallic sheet when either the black sheet or the metallic sheet is fed as the recording medium in the image forming apparatus.
