Abstract: An image forming apparatus includes an intermediate transfer member. The intermediate transfer member includes a layer made of an acrylic copolymer. A plurality of grooves is formed in the layer along a moving direction of the intermediate transfer member across a width direction of the intermediate transfer member. A groove distance that is an average distance between adjoining grooves of the plurality of grooves in the width direction of the intermediate transfer member is 2 μm or more and 10 μm or less.

Abstract: Provided is an electrophotographic belt sustainably excellent in toner removal performance. The electrophotographic belt has an endless shape and has grooves on an outer surface thereof, each of the grooves extending in a circumferential direction and being in non-parallel with the circumferential direction, and the outer surface is composed only of a first region in which the number of the grooves in a direction orthogonal to the circumferential direction is “n” and a second region in which the number of the grooves in the direction orthogonal to the circumferential direction is larger than the “n”, the first region and the second region being arranged alternately in the circumferential direction, and the “n” being an integer of 1 or more.

Abstract: An image forming apparatus includes an exposure device having an adjustment period for adjusting an output while exposing a photosensitive drum to light prior to image formation and a developing device. The developing device is configured to change between a contact state where the photosensitive drum and a developing roller are in contact with each other and a separation state where they are separated from each other. The developing device changes from the separation state to the contact state when a portion on the photosensitive drum exposed to light in the adjustment period of the exposure device is at a developing position.

Abstract: A transfer belt, to be used in a state of being in contact with a cleaning member and an image carrier, and to which a developer image is to be transferred from the image carrier, includes a surface layer and a base layer. The surface layer is in contact with the image carrier and the cleaning member. The base layer disposed at a position more apart from the image carrier and the cleaning member than the surface layer. The surface layer is provided with grooves formed by transferring a predetermined mold shape and extending in a first direction along a moving direction of the transfer belt in an operating state. The arithmetic average roughness of the surface layer in a predetermined region is less than or equal to 0.2 μm.

Abstract: An image forming apparatus includes an exposing unit, an intermediary transfer belt, a cleaning blade to clean a remaining toner on the intermediary transfer belt, and a controller to control so as to form a toner image on the intermediary transfer belt to supply toner as a lubricant of the cleaning blade. The controller controls a first line count when a first toner image is formed to supply the toner to the cleaning blade to become fewer than a second line count when a second toner image is formed to transfer to a recording material.
