Process cartridge and image forming apparatus

A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The cartridge includes an electrophotographic photosensitive drum, a developing roller, a drum unit containing the drum, a developing unit containing the roller and being movable so the roller contacts and is spaced from the drum, and a first force receiver receiving a force from a main-assembly first force applier by movement of a door from open to closed positions when mounting the cartridge and a second force receiver movable from a stand-by position by movement of the first force receiver by a force received from the first force applier. The second force receiver takes a projected position receiving a force from the second force applier to move the developing unit so the roller moves out of contact with the drum, the projected position being higher than the stand-by position.

A cartridge including: a first unit including an image bearing member and a first portion, and configured to take a removal posture when the cartridge is to be removed from a main body; a second unit including a developer bearing member and a second portion, the second unit being movable between a first position where the developer bearing member is in contact with the image bearing member and a second position where the developer bearing member is separated from the image bearing member and where the second portion is in contact with the first portion, wherein when the first unit takes the removal posture, the second unit is located at the second position, and when the second unit is located at the second position, movement of the second unit in a direction, in which the developer bearing member is separated from the image bearing member, is restricted.

Cartridge including a member movable relative to a frame of the cartridge and a regulating member for regulating movement of the movable member

A cartridge includes a photosensitive drum and a coupling member for transmitting a driving force to the photosensitive drum. A movable member is provided movable relative to a frame and a rotatable portion is supported by the movable member and rotatable relative to the movable member. A regulating member is movable between a regulating position for regulating movement of the movable member by contacting the rotatable portion and a non-regulating position where the regulating member does not regulate the movable member. A position of an end portion of the movable member in an axial direction of the photosensitive drum changes relative to the frame by movement of the movable member between a first position and a second position, and the end portion of the movable member is closer to the coupling member in the axial direction of the photosensitive drum when the movable member is in the second position than when the movable member is in the first position. When the regulating member is in the regulating position, the movable member is constrained from moving from the first position to the second position, and, when the regulating member is in the non-regulating position, the movable member is permitted to move from the first position to the second position.

Cartridge having toner removing sheet in contact with photosensitive drum

A cartridge detachably mountable to a main assembly of an image forming apparatus includes a photosensitive member unit including a photosensitive drum; a sheet configured to remove a deposited matter from a surface of the drum, the sheet being in contact with the surface of the drum at an end portion of the drum with respect to a rotational axis direction of the member; and a developing unit detachably mounted to the member unit, the developing unit including a developing roller configured to supply toner to the drum, and a storage portion configured to store the deposited matter removed from the surface of the drum by the sheet.

Image forming apparatus and process cartridge

An image forming apparatus includes a mounting portion for mounting a process cartridge, the process cartridge including a first unit having an image bearing drum, and a second unit having a developing roller, the second unit being movable between a contact position in which the roller contacts the drum and a spaced position in which they are mutually spaced; an engageable member engageable with a force receiving portion provided on the second unit; wherein the engageable member is movable between a first position for maintaining the second unit in the spaced position by engaging with the force receiving portion, a second position for permitting movement of the second unit from the spaced position to the contact position; and a third position for permitting the process cartridge to be mounted, by being pressed by the process cartridge to retract, when the process cartridge is mounted to the mounting portion.

A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The cartridge includes an electrophotographic photosensitive drum, a developing roller, a drum unit containing the drum, a developing unit containing the roller and being movable so the roller contacts and is spaced from the drum, and a first force receiver receiving a force from a main-assembly first force applier by movement of a door from open to closed positions when mounting the cartridge and a second force receiver movable from a stand-by position by movement of the first force receiver by a force received from the first force applier. The second force receiver takes a projected position receiving a force from the second force applier to move the developing unit so the roller moves out of contact with the drum, the projected position being higher than the stand-by position.

PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS

A process cartridge includes a first unit including an image bearing member configured to carry an electrostatic latent image, and a second unit including a developer bearing member configured to develop the electrostatic latent image carried on the image bearing member into a toner image, the second unit being capable of being mounted on the first unit in a mounting direction. The first unit includes a moving member that moves the second unit mounted on the first unit at a mounting position to a detachment position. The second unit includes a storage unit that stores information about the second unit The moving member is disposed on a first side of the process cartridge in a longitudinal direction of the image bearing member. An electrode of the storage unit is disposed on a second side of the process cartridge in the longitudinal direction.

IMAGE FORMING APPARATUS, PROCESS CARTRIDGES, AND CONNECTING MEMBER

[Task] To further develop conventional technique.

[SOLUTION] An image forming apparatus includes a main assembly; a plurality of process cartridges detachably mountable to the main assembly.

The apparatus further includes a connecting member 201 connecting at least two of the second frames of the process cartridges and removable from at least one of the process cartridges and from the main assembly.

Remanufactured Toner Cartridge and Method
20170329256 · 2017-11-16 ·

A remanufactured toner cartridge and related method includes a modified driven gear that is associated with an internal seal removal mechanism. The driven gear is modified so that driving rotational force from a printer is not transmitted to the seal removal mechanism during a post test of the remanufactured cartridge. When the post test is complete a fixing member, which may include a pin, is used to return the modified driven gear to an operational configuration so that when the cartridge is subsequently installed in a printer, driving rotational force from the printer is transmitted to the removal mechanism to remove the internal toner seal, thereby permitting cartridge operation.
