Abstract
An image forming apparatus to form an image on a sheet by permanent color toner and decolorizing toner to be decolorized includes a detector unit to detect whether a predetermined identification image to indicate execution of a image forming process by decolorizing toner is formed or not at least on either of a first side and a second side of a sheet which is a subject of the image forming process to be executed and a process controlling unit, when the predetermined identification image is detected by the detector unit, to prohibit the image forming process by permanent color toner on a sheet side on which the predetermined identification image is detected.
Claims19
An image forming apparatus to form an image on a sheet by permanent color toner and decolorizing toner to be decolorized, comprising:
- a detector unit to detect whether a predetermined identification image for indicating execution of an image forming process by decolorizing toner is formed or not at least on either of a first side and a second side of a sheet which is a subject of the image forming process to be executed;
- and
- a process controlling unit to prohibit the image forming process by the permanent color toner on the sheet side on which the predetermined identification image is detected when the identification image is detected by the detector unit.
An image forming apparatus to form an image on a sheet by permanent color toner and decolorizing toner to be decolorized, comprising:
- a mode discriminate unit, regarding an image forming process to be executed, to discriminate which is selected, a first mode to perform an image forming process by permanent color toner or a second mode to perform the image forming process by decolorizing toner;
- and
- an identification image forming unit, when it is discriminated by the mode discrimination unit that the second mode is selected, in the image forming process in which it is discriminated that the second mode is selected, to form a predetermined identification image to indicate execution of the image forming process by decolorizing toner on a sheet on which an image is to be formed by decolorizing toner.
An image forming apparatus to form an image on a sheet by permanent color toner and decolorizing toner to be decolorized, comprising:
- a mode discriminate unit, regarding an image forming process to be executed, to discriminate which is selected, a first mode to perform an image forming process by permanent color toner or a second mode to perform the image forming process by decolorizing toner;
- an identification image forming unit, when it is discriminated by the mode discrimination unit that the second mode is selected, in the image forming process in which it is discriminated that the second mode is selected, to form a predetermined identification image to indicate execution of the image forming process by decolorizing toner on a sheet on which an image is to be formed by decolorizing toner;
- a detector unit to detect the predetermined identification image formed by the identification image forming unit;
- and
- a process controlling unit, when the identification image is detected by the detector unit, to prohibit the image forming process by the permanent color toner on the sheet side on which the predetermined identification image is detected.
An image forming process controlling method for an image forming apparatus to form an image on a sheet by permanent color toner and decolorizing toner to be decolorized, comprising:
- detecting whether a predetermined identification image to indicate execution of an image forming process by decolorizing toner is formed or not at least on either of a first side and a second side of a sheet which is a subject of the image forming process to be executed;
- and
- prohibiting, when the predetermined identification image is detected, the image forming process by the permanent color toner on the sheet side on which the predetermined identification image is detected.
An image forming process controlling method for an image forming apparatus to form an image on a sheet by permanent color toner and decolorizing toner to be decolorized, comprising:
- discriminating, regarding an image forming process to be executed, which is selected, a first mode to perform the image forming process by permanent color toner or a second mode to perform the image forming process by decolorizing toner;
- and
- forming, when it is discriminated that the second mode is selected, in the image forming process in which it is discriminated that the second mode is selected, a predetermined identification image to indicate execution of the image forming process by the decolorizing toner on a sheet on which an image is to be formed by the decolorizing toner.
An image forming process controlling method for an image forming apparatus to form an image on a sheet by permanent color toner and decolorizing toner to be decolorized, comprising:
- discriminating, regarding an image forming process to be executed, which is selected, a first mode to perform the image forming process by permanent color toner or a second mode to perform the image forming process by decolorizing toner;
- forming, when it is discriminated that the second mode is selected, in the image forming process in which it is discriminated that the second mode is selected, a predetermined identification image to indicate execution of the image forming process by the decolorizing toner on a sheet on which an image is to be formed by the decolorizing toner;
- detecting the predetermined identification image formed;
- and
- prohibiting, when the identification image is detected, the image forming process by the permanent color toner on the sheet side on which the predetermined identification image is detected.
