Abstract: A charging device includes: a to-be-charged member; a charging member that charges the to-be-charged member and is opposed to the to-be-charged member; a cover member that surrounds the charging member disposed inside of the cover member but has an opening at a site opposed to the to-be-charged member; a grid electrode that is disposed on the opening side of the cover member with respect to the charging member, the grid electrode being provided between the cover member and the to-be-charged member; and a protective member that is provided along a longitudinal direction of the grid electrode, the protective member protecting an end part of the grid electrode and having at least one opening that is provided between the to-be-charged member and an end part of the cover member on the to-be-charged member side.

Abstract: A charger includes: a first electrode; a second electrode that has a mesh pattern and is arranged on a side closer to a photoconductor than the first electrode; a cleaner that moves along the second electrode to clean the second electrode by a brush thereof. The second electrode has the mesh pattern successively arranged in a certain direction, and a peripheral region of the mesh pattern of the second electrode has been changed to prevent catching of the brush of the cleaner.

Abstract: A droplet ejection apparatus includes: a droplet ejection head that ejects droplets; a conveying member that retains a recording medium and conveys the recording medium with facing the recording medium to the droplet ejection head; a coating member that coats the conveying member with a lubricant; and a cleaning member that cleans the conveying member. The droplet ejection apparatus satisfies the following formulae (1) L2?L1??(1) wherein, in the formulae (1): L1 is the width, in the direction orthogonal to the conveying direction, of the cleaning of the conveying member by the cleaning member; and L2 is the width, in the direction orthogonal to the conveying direction, of coating the lubricant on the conveying member by the coating member.

Abstract: In an image recording apparatus disclosed by this invention, a recording medium is conveyed to a recording head having recording unit groups each in which a plurality of the recording units for recording an image are arranged at a predetermined interval linearly at a predetermined angle with respect to a predetermined direction. When the recording medium is conveyed at a predetermined average velocity, an image recording start timing of each recording column is controlled with the recording units contained in a direction intersecting with the predetermined direction of the recording head as a recording column so as to form a linear dot string having an angle different from the predetermined angle in the recording medium by means of the respective recording units of the recording head.
