Abstract: An image forming apparatus, to which a cartridge including a developer accommodating portion for accommodating a developer is detachably mountable, includes an image bearing member, an exposure unit configured to expose the image bearing member to light to form an electrostatic latent image on the image bearing member, a light receiving sensor provided in the cartridge and configured to receive the light emitted from the exposure unit, and a controller configured to detect vibration of the cartridge from a light reception value of the light received by the light receiving sensor. In a case in which the cartridge is removed from the image forming apparatus, the light receiving sensor is removed from the image forming apparatus together with the cartridge.

Abstract: An image forming apparatus includes, an image forming portion configured to form a toner image on a sheet using printing toner and apply powder adhesive on the sheet, a fixing portion configured to heat the toner image formed on the sheet and the powder adhesive applied on the sheet by the image forming portion and fix the toner image and the powder adhesive to the sheet, and a bonding portion configured to bond the sheet with the powder adhesive by reheating the sheet having been heated by the fixing portion. The bonding portion is arranged above the image forming portion.

Abstract: The object of the present invention is to provide a magnetic toner enabling an image with high image density and excellent image reproducibility to be obtained, which is excellent in fluidity, charging stability, and charging uniformity, even for long-term use, and also enabling an image whose fogging, ghost, and scattering are suppressed to be obtained. The magnetic toner has at least a binder resin and a magnetic material, where, the magnetic material is an magnetic iron oxide whose dielectric breakdown voltage of the magnetic material is 160 to 1600 V/cm, and the dielectric loss tangent (tan ?) of the magnetic toner at 100 kHz and 40° C. is 2.0×10?3 to 1.0×10?2.

Abstract: The present invention aims to provide a toner having excellent developability and excellent low-temperature fixability without causing adhesion of ejected sheets even in a high-speed oilless fixing system and capable of preventing a frameless printing from causing a twisted offseting phenomenon. Specifically, provided is a toner having toner particles including at least a binder resin and a colorant, in which, when the toner is dissolved in a tetrahydrofuran (THF) solvent at 25° C. for 24 hours, the ratio of a THF-soluble matter having an intrinsic viscosity of 5.0×10?2 dl/g or less with respect to the total amount of the THF-soluble matter in a GPC-RALLS-viscometer analysis is 15.0 mass % to 60.0 mass %, and the ratio of a THF-soluble matter having an intrinsic viscosity of 1.5×10?1 dl/g or more with respect to the total amount of the THF-soluble matter in a GPC-RALLS-viscometer analysis is 20.0 mass % to 40.0 mass %.

Abstract: A telephone includes a telephone body, a handset and a telephone network line hold mechanism. The telephone body includes a handset cradle on which the handset is placed, a plurality of operation buttons and the like. The telephone is placed in the offhook state when the user lifts the handset from the handset cradle and placed in the on-hook state when the user places the handset on the handset cradle. The telephone network line hold mechanism is energized when the user places the handset on the telephone body at its position in which the offhook state of the telephone is retained.

Abstract: In a liquid crystal display device having a voltage-driven liquid crystal cell sandwiched between two spaced polarizers, the cell comprises a liquid crystal layer having a twisted molecular alignment with no applied voltage and also having an optical rotary power with respect to visible rays. In the vicinity of the cell or in close contact therewith, there is disposed an optically anisotropic layer having an optical rotary power smaller than that of the cell.
