摘要： A sheet conveying apparatus capable of conveying a sheet as a conveyance target in a conveyance path includes a detector that detects capacitance in a predetermined detection region in the conveyance path; and a basis weight identifier that identifies a basis weight of the sheet as the conveyance target on the basis of first capacitance detected by the detector while the sheet as the conveyance target does not pass through the detection region and second capacitance detected by the detector while the sheet as the conveyance target passes through the detection region.

摘要： An image forming apparatus includes: a photosensitive member; a charger that charges a surface of the photosensitive member; an exposure device that forms a latent image; and a developing device that applies toner to the latent image, wherein the photosensitive member is incorporated in a detachable photosensitive member unit, and the developing device is incorporated in a detachable developing unit, the image forming apparatus including: an optimization controller that performs optimization of a charging bias of the charger and a developing bias of the developing device; and a replacement determiner that determines which of the photosensitive member unit and the developing unit is to be replaced when an optimized developing bias is out of a predetermined allowable range, wherein the replacement determiner determines that the developing unit is to be replaced, and determines that the photosensitive member unit is to be replaced.

摘要： An image forming apparatus includes: a rotatable photosensitive member included in a photosensitive unit that is attachable and detachable; an exposing device that forms a latent image on a surface of the photosensitive member; a developing device that forms a toner image by providing toner onto the latent image by using two-component developer; an image stabilization control part that performs optimization of a parameter value of image formation while image formation is not performed; and a replacement determiner that makes determination of replacement of the photosensitive unit on a basis of an optimized value that is the parameter value optimized by the image stabilization control part, wherein the replacement determiner determines that the photosensitive unit should be replaced in a case where the optimized value corresponds to a photosensitive member replacement event that has been determined in advance.
