An image forming apparatus includes an image forming part, a scanner part to moving up and down with respect to the image forming part, and a pair of side walls located between the image forming part and the scanner part while facing each other, the pair of side walls including a fixed side wall supported by the image forming part and a lifting side wall to moving up and down with respect to the fixed side wall and supported by the scanner part.
COUPLING STRUCTURE AND IMAGE FORMING APPARATUS
A coupling structure is provided in an imager forming apparatus that forms an image on a recording material and configured to couple a first member and a second member. The second member includes a sheet metal having an insulative layer on a surface of a metal layer. A first conductive portion is formed in the first member. A second conductive portion includes a projection formed by press working in the second member. A coupling portion couples the first member and the second member in a state in which at least a part of the first conductive portion and at least a part of the second conductive portion are contacted with each other.
IMAGE FORMING APPARATUS
An image forming apparatus includes a frame, a top plate cover removable from the frame and having a top surface portion constituting a part of a top surface of the image forming apparatus, and a screw. The frame includes an upper surface portion opposite to the top surface portion, a front surface portion provided at a front side with respect to the upper surface portion, and a back surface portion provided at a back side with respect to the upper surface portion and provided with a through-hole. The top plate cover includes a first mounting portion fixed to the front surface portion, and a second mounting portion provided at a back side with respect to the first mounting portion and inserted into the through-hole. The screw is inserted in a front-back direction to fix the front surface portion of the frame and the first mounting portion.
Image forming apparatus having guide members for detachably inserting cartridges
An image forming apparatus includes: a first guide that is provided in an apparatus housing and configured to suspend and hold a first unit including an image holder so that the first unit is movable in an insertion and removal direction; a second guide that is provided in the apparatus housing and configured to suspend and hold a second unit including a developer holder so that the second unit is movable in an insertion and removal direction; and a pedestal that is disposed on a front side in the insertion and removal direction with respect to the first guide and the second guide, supports, from below in a gravity direction, the first unit and the second unit while the first unit and the second unit are inserted into the apparatus housing, and does not contact with the first unit and the second unit located in the apparatus housing.
IMAGE FORMING APPARATUS
An image forming apparatus including: an image forming unit configured to form an image on a recording medium: an upper surface cover which is provided to an upper surface of the image forming apparatus and forms at least a part of an appearance of the image forming apparatus; a first cover which is provided to a front surface of the image forming apparatus and forms at least a part of the appearance of the image forming apparatus; and a second cover which is provided to the front surface of the image forming apparatus so as to be located above the first cover and forms at least a part of the appearance of the image forming apparatus. The first cover includes a resin material. The second cover includes a ferromagnetic material.
IMAGE FORMING APPARATUS AND METHOD FOR PRODUCING DRIVE UNIT
An image forming apparatus includes a support frame, a driving device including a first supporting portion configured to hold the drive source on a first surface and configured to rotatably support the drive gear on a second surface, and a second supporting portion configured to support the drive gear with the first supporting portion, a board holding member disposed in a manner overlapping the first supporting portion in a rotational axis direction of the drive gear, and a third supporting portion disposed between the first supporting portion and the board holding member in the rotational axis direction, and configured to support the board holding member, one end of the third supporting portion being fixed to a side of the first surface of the first supporting portion by a first fastening member, another end of the third supporting portion being fixed to the board holding member by a second fastening member.
IMAGE FORMING APPARATUS CAPABLE OF SUPPRESSING DETERIORATION IN IMAGE QUALITY
An image forming apparatus includes a photoelectric conversion portion, a housing, a housing support portion, and a posture adjustment portion. The photoelectric conversion portion receives light reflected by a document sheet placed on a document sheet mounting surface and outputs an electric signal based on the light. The housing has a box shape with an open top and forms a housing space for housing the photoelectric conversion portion on a lower side of the document sheet mounting surface. The housing support portion supports a bottom portion of the housing. The posture adjustment portion includes an operation portion provided outside the housing, and adjusts a posture of the photoelectric conversion portion in accordance with an operation on the operation portion.
IMAGE FORMING APPARATUS HAVING TONER REPLENISHMENT
An apparatus includes a developer container to and from which a replenishment container is attachable and detachable and which includes an accommodating portion and a replenishment port, a transfer portion configured to transfer a developer image on an image bearing member onto a recording material, a supporting tray including a supporting surface configured to support the recording material thereon, and a discharge portion configured to discharge the recording material, onto which the developer image has been transferred, on the supporting surface, wherein the supporting surface has an opening portion opening such that the replenishment port is exposed through the supporting surface, and wherein an opening/closing member configured to be movable between a closed position where the opening/closing member covers the replenishment port and serves as a part of the supporting surface and an open position where the replenishment port is exposed is provided.
IMAGE FORMING APPARATUS PROVIDED WITH ABUTTING AND SUPPORT STRUCTURES
An image forming apparatus includes a photoconductor, a bearing body, an abutting portion, a support frame, an exposure device, and an urging body. The photoconductor includes a shaft portion at an end portion. The bearing body is configured to receive the shaft portion. The abutting portion is coupled to the bearing body. The support frame is configured to support the abutting portion and the bearing body. The exposure device faces the photoconductor, abuts on the abutting portion, and includes a light source exposing the photoconductor to light. The urging body is configured to press the exposure device toward the support frame, urge the abutting portion toward the bearing body and the shaft portion, and urge the bearing body toward the support frame.
IMAGE FORMING APPARATUS
An image forming apparatus includes an image forming unit and a power device. The power device includes a circuit board provided to intersect a horizontal plane. The power device includes an electrolytic capacitor, an electric element, and a plate-shaped member that is provided between the electrolytic capacitor and the electric element in a vertical direction and including a first surface extending in a second direction intersecting the vertical direction. The plate-shaped member includes a cutout or a hole, and a position of at least part of an area where the cutout or the hole is formed is farther in the first direction from the mounting surface of the circuit board than a position of the electric element.
