A carrier core material is provided that is formed with ferrite particles which can uniformly adhere a coupling agent to the entire surface. A carrier core material is formed with ferrite particles, and the powder pH of the ferrite particles is equal to or more than 9. Here, the ferrite particles are preferably formed of Mn ferrite or Mn&#x2014;Mg ferrite. The ferrite particles preferably contain 45 wt % or more but 65 wt % or less of Fe, 15 wt % or more but 30 wt % or less of Mn and 5 wt % or less of Mg.

Carrier core material

A carrier core material is represented by a composition formula MFeO(where M is Mn and/or Mg, and X is a total of Mn and Mg and is a substitution number of Fe by Mn and Mg, 0&#x3c;X&#x2264;1), in which 5 to 20 number percent of bound particles where 2 to 5 spherical particles are bound together are contained and in which the maximum peak-to-trough depth Rz of the surface of normal spherical particles other than the bound particles is equal to or more than 1.5 &#x3bc;m but equal to or less than 2.1 &#x3bc;m. In this way, it is possible to increase the amount of toner supplied to a development region, and the surface of a photosensitive member is prevented from being scratched by a magnetic brush.

Ferrite particles have, as a main component, a material represented by a composition formula MFeO(where M is at least one type of metal selected from a group made of Mg, Mn, Ca, Ti, Cu, Zn, Sr and Ni, 0&#x3c;x&#x3c;1), where the maximum height Rz of the particles falls within a range of 1.40 &#x3bc;m to 1.90 &#x3bc;m, and the degree of distortion Rsk of the particles falls within a range of &#x2212;0.25 to &#x2212;0.07. In this way, when the ferrite particles are used as the carrier of an electrophotographic image forming apparatus, even if an image formation speed is increased, the occurrence of a failure is reduced for a long period of time.

To reduce PAPR in an optical OFDM communication system, light is phase-modulated by a base-band OFDM signal which is the output of a transmission signal processing unitprovided in an inner section of an optical receiver. When optical communication is implemented with the light as signal light, PAPR of low level of almost 0 dB can be achieved at places in an inner section of an optical fiber wherein the optical power is large. The signal light is propagated along an optical fiber which is a transmission path, the light is passed through a delay interferometer, and converted to electrical signals by two optical receivers. Each of the two electrical signals is converted to a subcarrier by FFT signal processing and an AD converter disposed in an inner section of the optical receivers, then, subcarriers having the same frequency are subtracted and decoded, and data is regenerated.
