摘要:
A method and apparatus (1) of image forming include a process cartridge (50) detachably mounted therein. The process cartridge (50) includes a photoconductive element (25y,25c,25m,25bk) and a housing (53,54) storing the photoconductive element and including a guide portion (60,70) guiding the process cartridge. The guide portion (60,70) faces an inner wall of the image forming apparatus (1) or another process cartridge (50) adjoining thereto. The guide portion guides the process cartridge adjoining and is slidably engages with a portion of said process cartridge adjoining. The guide portion varies in shape according to a position in the image forming apparatus. The guide portion is separately formed from or integrated with the housing. A method and apparatus (1) of an image forming includes an image transfer mechanism (22) and a plurality of process cartridges (50) arranged in line in parallel. Each of the process cartridges (50) includes photoconductive elements (25) and a housing (53,54), and forms an image for a single separated color.

A cleaning device (25) to remove untransferred toner from a surface of an image carrier (21) rotatable in a predetermined direction. The cleaning device (25) includes a lubricant supply roller (25d) contacting the surface of the image carrier (21) to supply a lubricant carried thereon to the surface of the image carrier (21), a first blade (25a) provided upstream from the lubricant supply roller (25d) in the direction of rotation of the image carrier (21), and a second blade (25b) provided downstream from the lubricant supply roller (25d) in the direction of rotation of the image carrier (21). The first blade (25a) contacts the surface of the image carrier (21) to level the untransferred toner attaching to the surface of the image carrier (21) to a thin layer. The second blade (25b) contacts the surface of the image carrier (21) to level the lubricant supplied to the surface of the image carrier (21) by the lubricant supply roller (25d) to a thin layer and to remove the untransferred toner from the surface of the image carrier (21).

An image forming apparatus (100) includes a main body (101), and a process cartridge (30) detachably disposed in the main body (101) and including an image bearing member (1) configured to bear an image on a surface thereof and rotate at a predetermined linear velocity, and a lubricant applying member (17a) disposed in contact with the image bearing member (1) and configured to apply a lubricant (17b) on the surface of the image bearing member (1) while rotating with the image bearing member (1), wherein the lubricant applying member (17a) includes a brush roller (17a) and is controlled to rotate at a linear velocity different from the predetermined linear velocity of the image bearing member (1) at a contact portion with the image bearing member (1) so that the lubricant applying member (17a) applies an amount of the lubricant (17b) smaller than an amount of lubricant used when the image bearing member (1) and the lubricant applying member (17a) rotate at an identical linear velocity.

摘要:
An image forming apparatus (100) includes a unit (10Y), a mark detector (103Y), and a controller (200). The unit is attachable to and detachable from the image forming apparatus and includes an information mark pattern (102Y) indicating predetermined information. The mark detector detects the information mark pattern. The controller obtains the information indicated by the information mark pattern based on a detection result provided by the mark detector.
摘要:
An image forming apparatus includes an endless transfer member and a plurality of image forming units. The endless transfer member is arranged at a transverse position in the image forming apparatus, and has a circulatory rotating lower surface at a predetermined angle to a horizontal plane declining in a rotation direction of the endless transfer member. The plurality of image forming units perform a color image forming operation and are arranged next to one another under and facing the endless transfer member such that, in any two immediately adjacent image forming units of the plurality of image forming units, one of the any two immediately adjacent image forming units at an upstream position in the rotation direction of the endless transfer member has a portion overhanging the other one of the any two immediately adjacent image forming units. An image forming method is also described.
