摘要： A transfer device includes a holding body, a transfer body, and a setting portion. The holding body holds multiple layers including a base layer formed of a toner having a mass larger than a threshold. The toner is electrically charged by a charging device. The transfer body transfers the layers on the holding body to a recording medium. The setting portion sets the charging device so that the charging device electrically charges a toner immediately after being transferred to the holding body with a larger amount of electric charges when the base layer is located uppermost on the holding body, than when the base layer is located other than uppermost on the holding body.

摘要： An embodiment provides an image forming apparatus that has a first operation mode and a second operation mode. The first operation mode forms an image on a sheet with toner. The second operation mode decolorizes the toner on the sheet on which the image is formed with a decolorable toner having a decoloring function. In the first operation mode, when the sheet passes through a transfer unit, a transfer bias having the same polarity as that of a charge of the toner is applied to the transfer member and a toner image formed on a surface of the transfer member is transferred to the sheet. In the second operation mode, when the sheet passes through the transfer unit, a cleaning bias having a reverse polarity to that of the transfer bias is applied to the transfer member.

摘要： An image forming apparatus includes an image bearing member configured to bear a toner image formed using a liquid developer containing toner particles and a carrier liquid, a transfer member, an input portion into which information on a kind of a recording material is inputted, an adjusting device configured to adjust an amount of the carrier liquid of the toner image, and an executing portion configured to execute an operation of the adjusting device depending on the information when the toner image is in the adjusting position. The executing position executes either of a plurality of operations including a first operation in which the amount of the carrier liquid of the toner image is increased, a second operation in which the amount of the carrier liquid is decreased, and a third operation in which the amount of the carrier liquid is not adjusted.

摘要： Provided is an elastic member which is obtained by forming a resin coating layer on at least a part of the surface of a base that is formed of an elastic material, and which is characterized in that the resin coating layer is a coating film that contains 1.5-45 parts by mass of a low-friction powder per 100 parts by mass of a base resin and has a 100% modulus of 22-30 MPa. This elastic member has a resin coating layer that has a good balance between film formability and low friction, and is suitable as a sealing member for an opening part of a toner container that is provided on a toner cartridge of a printer, a copy machine or the like.

摘要： An image forming apparatus includes an image carrier, a removal roller, a collection roller, a housing, a screw, and a seal. The removal roller rotates while in contact with the intermediate transfer belt and removes residual toner from the intermediate transfer belt. The collection roller rotates while in contact with the removal roller so as to collect, from the removal roller by electrostatic force, waste toner that is the residual toner removed by the removal roller. The housing has an upper opening for receiving the waste toner collected by the collection roller and stores the waste toner. The screw conveys the waste toner stored in the housing. The seal comes into contact with the collection roller and closes a gap between the collection roller and the housing at the upper opening.

摘要： A transfer device includes an image bearer, a rotatable body, a solid lubricant assembly, and a guide. An image bearer bears an image. The rotatable body forms a transfer nip with the image bearer to rotate in contact with a recording medium. An image on the image bearer is transferred onto the recording medium at the transfer nip. The solid lubricant assembly includes a solid lubricant and extends in a longitudinal direction of the rotatable body. The solid lubricant assembly applies a solid lubricant to at least one of the rotatable body and the image bearer. The guide guides the recording medium and positions the solid lubricant assembly.
