摘要： A structure for a transport path for a recording material within a transfer portion varies between a margin-less print mode and a normal print mode. A necessity of cleaning of a transfer member also varies between both modes. Thus, provided is an image forming apparatus in which the structure of the transfer portion is switched between the normal print and the margin-less print, and the margin-less print cannot be carried out with a structure of the transfer portion for the normal print. This is because, when the so-called margin-less print is carried out with the structure of the transfer portion for the normal print, there is a possibility that an image defect of a print image to be outputted is caused, or a stain of toner on a rear surface of the recording material is caused.

摘要： A color image forming apparatus includes a first density detecting unit for detecting a density of a first detection toner image formed on an image bearing member or a transferring material carrying member, and a second density detecting unit for detecting a density of a second detection toner image fixed onto a transferring material, and executes image density control based on a detection result of the first density detecting unit and a detection result of the second density detecting unit. A detecting light application position of the first density detecting unit and a detection light application position of the second density detecting unit are almost equal relative to a perpendicular direction to a transferring material conveying direction. It is thereby possible to shorten time required for density control and to prevent deterioration of density control accuracy caused by a temporal change and a positional change in the density of a detection toner patch.

摘要： A color image forming apparatus and related method forms a color image on a transfer material. The apparatus is provided with a first optical sensor capable of detecting optical reflection characteristics of an unfixed toner image and a second optical sensor capable of detecting optical reflection characteristics of a toner image after fixation. A first forming step forms a mixed-color toner image including plural toners. A calculation step calculates, based on optical reflection characteristics of the mixed-color toner image detected by the second optical sensor, a condition that the mixed-color toner image becomes achromatic. A second forming step forms a toner image corresponding to the calculated toner mixing ratio. A processing step processes an output of the first optical sensor based on the optical reflection characteristics of the monochromatic toner image detected by the first optical sensor.
