An image forming apparatus includes an image forming unit that forms, when forming an image with a white toner on a colored recording medium, a base toner layer and a white toner layer in an overlapped manner such that the base toner layer is inserted between the white toner layer and the colored recording medium, and a fixing unit that fixes the base toner layer and the white toner layer that are formed by the image forming unit on the recording medium.

An image forming apparatus includes an image forming unit, an input unit and a control unit. The image forming unit forms an image by using a plurality of consumables. The input unit receives an input of information designating the consumables to be used for forming the image. The control unit selectably displays other candidates of the consumables to be used for forming the image, based on the designated consumables.

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.

An image forming system includes: a reader including a reading sensor that optically reads a sheet conveyed through a conveyance path; and a hardware processor that controls the reader, in which the reader is able to execute a plurality of reading modes including at least a first reading mode and a second reading mode different from the first reading mode, and reads the sheet in any one of the reading modes selected according to a print setting, and the hardware processor varies an image formation timing of forming an image on the sheet by an image former between when switching of the reading modes is performed and when the switching of the reading modes is not performed.
