摘要： PURPOSE:To eliminate the color staggering of a multi-colored electrostatic picture by giving a charge of a polarity reverse to a toner on a transfer material, switching appropriately voltages of the same and reverse polarities so as to impress them on a transfer drum, attracting and fixing the transfer material. CONSTITUTION:An image of a negatively charged toner 9 is formed on, for instance, a selenium photosensititve drum 10. A transfer drum 30 is so constituted to provide a conductive elastic layer 4 and an insulating layer 5 on a conductive base body 3, and said drum 30 is brought into contact A with the photosensitive drum. A transfer material 10 is advanced so shown by an arrow D. The surface of said material is positively charged by a corona discharge device 7, and the toner 9 is transferred at the drum contact part A. First, a negative voltage 6 is impressed on the transfer drum 30, and the transfer material 10 is attracted to be would on the drum 30. After the transfer material 10 passes through the contact part A by several tenmm., a positive voltage 6' is impressed on the transfer drum 30, and the toner is further attracted. Moreover, after the transfer material 10 is wound on the drum 30, it is securely fixed and will not move. Therefore even if colors of the toner are sequentially changed, the dark multi-colored picture can be obtained without the color staggering.

摘要： PURPOSE:To eliminate the color deviation of multi-colored pictures by giving the charge of a polarity same as a toner at the rear surface of a transfer material, impressing a reverse polaritly voltage to a transfer drum and attracting the transfer material so as to fix it. CONSTITUTION:For instanct, an electrostatic image is exposed on a selesium photosensitive drum 10' to form the image of a toner 9 negatively charged. A transfer drum 30 is so constituted to provide a conductive elastic layer 4 and an insulating layer 5 on a conductive basic material 3. Said transfer drum 30 is impressed by a positive bias voltage 6 and is brought into contact with the photosensitive drum 10' at a contact point A. A transfer material 10 is supplied as shown by an arrow D, and the rear part of said material is nagetively charged by a corona discharge device 7. When the transfer material 10 is entered to the contact part A of the drums 10' and 30, transfer is conducted on the transfer material 10 since the negative toner 9 is attracted to the transfer drum 30. Moreover, the negative transfer material 10 is attracted to the positive transfer drum 30 and securely fixed on the drum. Consequently, even if colors of toner are sequentially charged, the multi-colored picture without color deviation can be obtained since the transfer material is fixed on the drum.
摘要翻译：目的：为了通过在转印材料的后表面处提供与调色剂相同的极性的电荷来消除多色图像的颜色偏差，向转印鼓施加反向极化电压并吸引转印材料以固定它。构成：为了实例，将静电图像暴露在铯感光鼓10'上以形成带负电荷的调色剂9的图像。转印鼓30被构造成在导电基材3上提供导电弹性层4和绝缘层5.所述转印鼓30被正偏置电压6所压迫，并与感光鼓10'接触接触点A.如箭头D所示供给转印材料10，并且所述材料的后部通过电晕放电装置7进行充电。当转印材料10进入鼓的接触部分A时如图10'和图30所示，由于负性调色剂9被吸引到转印鼓30上，所以在转印材料10上进行转印。此外，负转印材料10被吸引到正性转印鼓30上并牢固地固定在转鼓上。因此，即使调色剂的颜色顺序充电，由于转印材料固定在滚筒上，所以可以获得没有颜色偏差的多色图像。

摘要： PROBLEM TO BE SOLVED: To reduce speed fluctuation of an image carrier for preventing a disturbance in an image due to the speed fluctuation in an image forming apparatus including the image carrier that carries an image and a transfer roller contacting with the image carrier and having a recessed portion in its circumferential surface, and in a method of forming an image by using the image forming apparatus.
SOLUTION: The image forming apparatus includes: the image carrier that carries an image; and the transfer roller which has the recessed portion in its circumferential surface and rotates around the rotation axis. In the transfer roller, the circumferential surface different from the recessed portion comes into contact with the image carrier and transfers the image onto a recording material. The circumferential surface of the transfer roller, which is different from the recessed portion, comes into contact with the image carrier due to rotation of the transfer roller while the rotational axis of the transfer roller moves away from the image carrier.
