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.

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.

In an MFP, when a count of printed sheets of paper exceeds a predetermined count, a controller reads, from internal counters, a frequency of a stabilization process executed in return, a frequency of a stabilization process executed automatically in printing, a frequency of a stabilization process executed manually based on a user's instruction, and a frequency of return, respectively. When the frequency of the stabilization process executed automatically is small while the frequency of the stabilization process executed manually is large, the controller raises a frequency level of execution of the stabilization process. When the frequency of the stabilization process executed manually is small, the controller lowers the frequency level of execution of the stabilization process.
