摘要： Toner used for electrophotographic development includes additives such as inorganic fine particles, having a particular particle diameter and specific surface area, and hydrophobic silica having a particular specific surface area and surface treatment, so that the toner can provide images of high quality without generating photoconductor filming. The toner is applied to the electrophotographic method including the developing step of forming electrostatic latent images on a photoconductor containing a stationary magnet, magnetically attracting the toner to the surface of the photoconductor in a toner sump, and collecting toner at a non-image section by an electrode roller; the transferring step of transferring the toner to transfer paper; the cleaning step of removing residual toner left on the photoconductor in the transferring step; and the recycling step of recycling the residual toner. Toner used for an electrophotographic method using an intermediate transfer member includes additives such as inorganic fine particles, having a particular particle diameter and specific surface area, arid hydrophobic silica having a particular specific surface area and surface treatment, so that the toner can provide images of high quality and high transfer efficiency without generating photoconductor and intermediate transfer member filming.

摘要： An oil application roller unit including a holder having at least a shaft or bearings, an oil application roller rotatably supported by the holder, and an oil leakage prevention film closely wound around the oil application roller to pack the roller and capable of being pulled out. By pulling the oil leakage prevention film while the oil application roller remains installed in the holder, the oil application roller is rotated, and the oil leakage prevention film can be removed. Since the user is not required to make contact with the oil application roller at the time of unpacking, the hands of the user are not stained. Unpacking can thus be attained safely.

摘要： A fixing device capable of suitable fixing even after moving to a print mode by reducing overshoot at moving to a print mode, and an image forming device using this. A mode switching unit informs a set or switched print mode to a calorie control unit and a rotation speed control unit. The calorie control unit controls supply power to a fixing roller, a heating roller and a fixing belt, that is a heating output from a heating means consisting of the fixing roller, the heating roller and the fixing belt according to a print mode informed from the mode switching unit. Therefore, the image fixing temperature of a non-fixed image at the heating means can be maintained at a specified temperature corresponding to a print mode.
