摘要:
There is provided a cleaning device for an image-forming device configured so as to be capable of preventing the image quality from deteriorating by being able to prevent the deterioration of the charging state caused by deposits of foreign matter without increasing costs. There is also provided a cleaning member that can make contact with the cleaning target-members. The cleaning member has a portion composed of melamine resin foam for making contact with at least the cleaning target members, and the melamine resin foam has an Asker F hardness of 5 to 25 points and a hardness variation of 5 points or less, and is used on the cleaning target members in a state obtained by heat compression from the original shape. The pressing member is furthermore disposed in contact with the cleaning member.
摘要:
A charging device, a process cartridge, and an image forming apparatus are provided. The charging device includes a charging roller configured to charge an image carrier and a cleaning roller configured to clean the charging roller while making contact with a surface of the charging roller. The charging device further includes a bearing member including a first portion configured to rotatably support a rotational shaft of the charging roller and a second portion configured to rotatably support a rotational shaft of the cleaning roller. The charging device also includes an elastic member provided outside of the second portion of the bearing member with respect to an axial direction of the rotational shaft of the cleaning roller such that the charging roller makes contact with the image carrier when the first portion of the bearing member is pressed by the elastic member.

An image forming apparatus includes an image carrier, a charging unit that charges the image carrier, a latent image forming unit that forms a latent image on the image carrier, a developing unit that develops the latent image to form a toner image, a transferring unit that transfers the toner image to a recording medium, a cleaning unit that cleans toner remaining on the image carrier, a lubricant applying unit that applies a solid lubricant to a surface of the image carrier, and a detecting unit that detects whether the image carrier is brand new. The toner has an average roundness of 0.94 or more. The lubricant applying unit is operated when the detecting unit detects that the image carrier is brand new.
