Abstract: A cleaning device includes a cleaning component that cleans the surface of a charging component that charges an image carrier that has a surface on which an electrostatic latent image is to be formed. The cleaning component is a hollow body that cleans the surface of the charging component while being rotated by rotation of the charging component.

Abstract: A neutralization device is disposed in an image forming apparatus having an image carrier so as to face the image carrier. The device comprises: a light irradiation section that irradiates neutralization light onto the image carrier; a case member that accommodates the light irradiation section and is opened to a side facing the image carrier; and a buffer member that is provided between the case member and the image carrier and prevents the light irradiation section from abutting against the image carrier.

Abstract: The image forming apparatus includes two tension rollers; a conveyor belt movably supported at the two tension rollers; a plurality of transfer parts that are arranged on the back surface side of the conveyor belt and between the two tension rollers, that contact one surface of the back surface of the conveyor belt, and that form a predetermined clearance with an opposite portion of the back surface of the conveyor belt; and a cleaning blade for removing residual toner remaining on the conveyor belt. The cleaning blade has the front end contacting the conveyor belt at a predetermined pressure. The cleaning blade is arranged at a position where the back surface of the conveyor belt distorted by the front end does not contact the tension roller.

Abstract: An IOT controller of an image formation device is provided with an NvRAM. Correction coefficients relating to various parameters, which are specified for each of paper types in advance, are stored in the NvRAM. The NvRAM is provided with a user setting region, and when it is desired to form an image at an unusual paper, parameters of this paper can be inputted by operation of a control panel. When image formation is to be implemented, the IOT controller, after selection of a paper type at the control panel, reads out correction coefficients of the parameters relating to the selected paper type from the NvRAM, implements transfer processing in accordance with these correction coefficients, and forms a high-quality image.

Abstract: Disclosed is an image forming apparatus which is compact and inexpensive, and which allows cleaning of a final transfer member. The image forming apparatus includes: an image bearing member; an image forming unit that forms a toner image on the surface of the image bearing member; an intermediate transfer device formed by at least one intermediate transfer member, and which is in contact with the image bearing member; a final transfer member which is in contact with the intermediate transfer member; a cleaning member which is in contact with the intermediate transfer member; and a control unit that controls the potential gradient between the image bearing member, the intermediate transfer member, the final transfer member, and the cleaning member, in which the control unit forms in an image formation mode a potential gradient for image formation which causes reverse-polarity toner on the final transfer member to adhere to the cleaning member by way of the intermediate transfer member.
