摘要： In a cartridge, a housing has a developer accommodating portion and includes a first side wall and a second side wall. A coupling member is disposed at a position opposite to the developer accommodating portion with respect to the first side wall. A detection body is disposed at a position opposite to the developer accommodating portion with respect to the second side wall. A first driving force transmission member is positioned at the same side with the coupling member with respect to the first side wall, and transmits driving force from the coupling member to a rotating member. A second driving force transmission member is positioned at the same side with the detection body with respect to the second side wall, and transmits driving force from the rotating member to the detection body.

摘要： An image forming apparatus includes a drum cartridge and developing cartridge. The drum cartridge may include a photosensitive drum rotatable about a first axis extending in an axial direction. The developing cartridge may include a developing roller rotatable about a second axis extending in the axial direction. The image forming apparatus may include a main casing including a slot extending in the axial direction. The image forming apparatus may include a first inner surface positioned inside of the slot, and a second inner surface positioned inside of the slot farther from the cover in the axial direction than the first inner surface from the cover in the axial direction. The first and second inner surfaces may be configured to press the developing roller toward the photosensitive drum.

摘要： An image forming apparatus includes a rotatable image bearing member, a developing member to develop an electrostatic latent image at a developing portion, a transfer member to transfer a developer image to a recording member at a transfer portion; and a brush provided with a plurality of base materials contacting the image bearing member at downstream of the transfer portion and upstream of the developing portion in a rotational direction of the image bearing member. The developer remaining on the surface of the image bearing member is collected in the developing portion. An average distance between base materials of the brush with respect to a rotational axis direction of the image bearing member is larger than an average particle diameter of the developer, and is equal to or less than a length corresponding to a special frequency visually recognizable by a user when the image formed by the image forming apparatus is observed by the user.

摘要： An image reading device includes a lens mirror array, a photoelectric conversion section, and a diaphragm section. The lens mirror array includes a plurality of optical elements. Each of the optical elements includes an incident-side lens surface, an upstream-side reflection surface, a downstream-side reflection surface, an emission-side lens surface, and a stray light reflection surface. The incident-side lens surface transmits and converges reflected light from a read surface. The upstream-side reflection surface reflects light made incident via the incident-side lens surface. The downstream-side reflection surface reflects the light. The emission-side lens surface transmits and converges the light and images the light on an imaging surface. The stray light reflection surface reflects stray light. The photoelectric conversion section receives, photoelectrically converts, and outputs the reflected light. The diaphragm section is disposed between the read surface and the incident-side lens surface and includes a slit-like opening section.
